More Midi Whoa's - Sonar Crashing

Sounds like it could be driver-related. Which interface are you using?

Ive done a few tests I tried creating a new main project folder with a version of project, which again plays fine, until I insert a new track of any type it now seems, audio, midi or soft synth track, so not isolated to soft synth, and the same issue occurs? Again oddly this only seems to happen with this particular project/set of tracks, no others, so far. Its like its not allowing me add anything to this project. I guess next I could go through deleting tracks to see if its related to one particular track. Weird?

Sound like you're on the right track (no pun intended).  It certainly seems like the project or one of the components has gotten corrupt.  Without knowing exactly what part, copying tracks to a new project could be pointless, so yeah, probably best to try and isolate the offending track/component.

Thanks all for replies, sorry was out in the cold for a while, -25 degrees Celsius here today, brrrrrr, ( I guess I should create a list of all my equipment, etc. in my signature). Some files/tracks were done on my old computer, and transferred over (as were most of my other projects).
 
Win 7 X64, Sonar Platinum x64 (Manchester), X99 based system, 5820 CPU (6 core, 12 hyper), 16 Gig ram, running Windows and Sonar/plugin's, from a primary 500 gig SSD. Little CPU usage showing on 12 CPU Sonar performance meters.  (and RME UFX), 
 
Its only 25 tracks, so not my largest, 24 bit, 96K sampling, only 3 are midi synths currently,  Addictive Drums, Addictive Keys, and Dimension Pro 9 (sax), rest are analog, some were bounced to analog from original midi synths, otherwise basic ProChannel plug-ins on most tracks, EQ, tube, Comp, limiter, and reverb and delay as send to buses, so nothing extreme than any other projects I've done.
I've done a number of save as scenario's, (and creating new project folders) and gone back a number of versions of project (now on Ver. 65, from original guitar, and Addictive drums tracks). As noted I may just be re-saving corrupted files.
Anyway at this point Ill I guess Ill try going a number of versions and/or try weeding out track by track to see if a particular track or tracks are to blame, this could be quite a long process, particularly if not one track alone causing it. Ill try and report back if I resolve it.
 
Otherwise I guess there's nothing specific I could look for that may somehow affect the record/playback/transport controls functions? Say like in configuration file or other preference settings or elsewhere in track and/or clip investigator?
 
cheers
 
    
 
 

Hey Zargg, FYI I tried the suggested fix to "Stackhash" error, which was to deactivate DEP, Data Execution Prevention, by listing exe file (Sonar) in an exclusion list, however returns a message to the effect, that 64 bit executable cant be excluded.
