Need some help concerning one Sonar X3 crash (IK Sampletank 3 is the cause)

Hello to everybody,
 
Here are my spec :
Sonar X3 d
Proc : i7, Windows 64 bits, Ram :12 gb
System Roland VS700 (console and soundcard)
 
Sorry to come again with problems but I worked on a project (containing audio tracks and 3 virtual instruments) without problem, until I open an instance of Sampletank 3 : I tried some stuff in it, changing (carefully) some instruments but one by one or maybe two maximum at the same time, BUT after about 20 minutes, Sonar stopped suddenly and I was forced to close the project and restart everything : computer, console and sound card.
When I re-open the project, I got a full scan of all my plugins and vsti, and after, a little window appeared : SONARPDR  with below the name of one plugin of my project and a step loading process : That took time !
BUT THE BEST is : when I play my project, the tracks are read but I have absolutely no sound coming from my sound card (??)
I tried with a pair of other projects and (except the little windows SONARPDR which appeared for one) everything is normal !
 
Would you have any idea of the problem ? It's not the first time that Sampletank 3 causes crashes but I never experienced the troubles I described after this crash !
 
Do you think that if I make a system restore point corresponding to before the incident could bring back to my system I found rather stable ?
 
Thank you very much for your appreciated help !
 
Pierre
 

Thanks much scook for the suggestions !
I always used the VST2 version of ST3 considering all the problems reported in the forum with the VST3 version.
As for X3e, I 'm a little bit reluctant regarding some problems mentionned and as long as I was "rather satisfied" with the satbility of the version d.
I noticed I have the Sampletank version 3.0.2 (4H27) and there is a version 3.0.3 (but nothing new in this version is related to stability improvement...)
Would you have an idea why I have no sound from this particular project ?

OK thanks, but nothing works ! I have the feeling that I cannot read anymore this project and there is something deeper in the system which is wrong !
Does the idea of recovering a system restore point is good ? Or by doing that, is there a risk of further destabilizing the system ??

Is the problem only with Sampletank?
Aside from X3e are the machine OS and drivers current?
This may be the tipping point to move to X3e rather than regressing to a previous state.

Thank you very much for your advise !
I have no particular problem with my VSTi (except sometimes some little bugs) BUT Sampletank 3 crashed systematically Sonar, and in a "vicious" manner   because it is only after about quarter of an hour that Sonar stops. Nevertheless, I could re open the projects, but this time, it is more serious ! (I made a support ticket to IK).
 
Craig, sorry for my ignorance, but  reverting to a system restore point could not cause trouble in the system ?

Hi Pierre,
I´m running ST 3 and Sonar X3e  pe here and have no probs.
Sorry, if I ask the obvious, cause immo st3 is ressource hungry:
Did you have during mixing aso
-Anti virus off ?
-Anti spam off ?
- did you freeze  tracks ?
- windows defender off aso?
- sequencer,samples and projects on the same hd ?
Have you optimized your box (windows) for music production?
Which buffersize/ driver ?
 
Have fun
Piet
 
 
 
 

First of all,sorry for not replying sooner and thank you very much for all your suggestions and help !
I opened the project in Safe mode and the play back worked normally ! In fact, as I described, when opened in no safe mode, there was a little window : SONARPDR and below there was the name of the Plugin "Master Violin" (the Violin from Gipsy East West) and a progression bar with step numbers 1 to 19xx, and, after this rather long step progression loading expires, the project and Sonar crashed, and I had to restart everything : computer, and all the VS700 system ...
In safe mode, I unselected the East West plugin, and things seem to be normal now. So, I presume that if I use the East West instrument, I have to FREEZE the plugin or bounce to audio track before I close the project ??
The problem is if the crash occurs suddenly when working on the project : It was the case with SAMPLETANK 3, but also, systematically with RAPTURE and DIMENSION PRO on another projects ! And for example, yesterday, I was jamming with BEATSCAPE which I know is at 32 bits version, and whereas I never had problems before with it, Sonar stopped ...
If someone has any idea ?
I made all the Windows updates as suggested and see if there are some improvements ! Will make a image backup system and go to the version D...
 
I forgot to say also that I have all the SONAR previous versions (from Producer 8.5 to X2). Apparently, I had never problems but maybe it could be best to remove them : For a clean remove : Do I have to go to the uninstall process in the Configuration Pannel of Windows 7 ? Or do I have to make another thing ?
 
Answering to Piet :
Did you have during mixing aso
-Anti virus off ?  : Yes
-Anti spam off ?  : Yes
- did you freeze  tracks ?  : Not systematically above all when I work late on a project; But never experienced too much problem and particularly with Kontakt 5, Spectrasonics, UVI...
- windows defender off aso? : I know that I have the Windows Firewall activated but it's all.
- sequencer,samples and projects on the same hd ? : No everything (c/system; plugin and samples; audio files) is separated in its own hd !
Have you optimized your box (windows) for music production? Yes, my computer is exclusively devoted to music production.
Which buffersize/ driver ? 256 (I think) and Asio with Roland VS 700 drivers (but unfortunately no more support for them)
 
Thanks again for your kind attention
 
Pierre

Thanks Pragui !
 
Just one interrogation : In the folder of this Cakewalk project, I have a "msdia80.dll" file (??) : Any idea of what is it ?

Thanks Pragi very much !
I contacted (for the 1rst time) the Cakewalk support (Joey Adams) who seems to be very reactive ! He asked me for the ".dmp" file. I hope main problems will be discarded !
