Wave preview, but no wave recording in X2 and X1

It drives me crazy!! I can record, see the preview waveform but when I hit stop, or even pause (tried to be smarter than X2), it is gone! There is not any sound recorded.
I tried all the stuff in the forum to solve my problem, without any results. See for example http://forum.cakewalk.com/FindPost/1892872 and  http://forum.cakewalk.com/FindPost/2819316
 
I have this problem in X1 and X2, but not in 8.5.3.
So for the moment I record in 8.5.3, the only way for me to work around. 
 
Can somebody help me?

Brundlefly, that was a very good idea and there was a weird action!
I created a new project and in the audio folder I saw 12 files: .....,Rec (1) to ,Rec (12).
In the picture cache there was a file 7A10.tmp .
 
Then I started recording, during the recording nothing changed in both folders, even with F5 refresh.
But, when I stopped recording, there was a new file in the audio folder ..., Rec (13).wav and in the picture folder two new files ...WTR and ...WOV.
And...(of course) the wave was in X2 and I could still hear it during playback!
 
So, everything is normal, but what is wrong with my project?
I made it in 8.5.3 and migrated to X2 to work further with it, including recording new voices. Every change or new sound (midi/instruments) works fine, but no audio recording. I watched both the folders from my project when I tried to record now in my own project.
Before recording, track armed, there were 5 files in the audio folder: ...,Rec (3534) to ..., Rec (3538), each 4 kB, and in the picture cache one file 12.tmp (empty).
During recording the wave was nice pictured in X2. After stopping the recording the wave was gone again as usual, and in the audio folder the 5 files were replaced by new files, also each 4kB and with names ..., Rec (3539) to ..., Rec (3543).wav
In the picture cache after disabling recording knob, the picture file was gone.
 
So I am really wondering what is happening here.
 
 

Brundlefly, thanks for your patience.. I noticed thanks to your suggestions, that some tracks in the project have 32 bit depth, but most tracks have 24 bit, the standard for me in my options. Sonar 8.5.3/X1/X2 have all the same options in samplerate, Record bit depth and audio driver bit depth (64 bit double precision). Could that cause problems, if you have in your project 'mixed' audio tracks from 24 and 32 bit depth?
 
I tried another old projcet I made in 8.5.3 - which had only 32 bit audio tracks - and added a new audio track 24 bit in X2. I could record and there was a wave after that! So maybe it is a matter of different bit depths? Though I could record in 24 bit with older audio tracks in 32 bit.
 
Tomorrow I will do your other suggestions.
 
I contacted Cakewalk Support, mentioned the problem with recording audio in X1/X2 but not in 8.5.3, but the answer is only for X2 (check audio card and reinstall X2), so I will send them the new found information about recording in a new project that works well in X1/X2.

This has to be said.
 
Dave (Brundlefly) has never been flashy. He is quiet and unassuming. I have never seen him bash anyone or cause any conflict. What he has done through all these years is post some of the very best posts of anyone and answer questions brilliantly. He does this over and over again. Here in a highly creative way he has out done himself and provided a recipe for the OP that is both insightful and brilliant. Yet its offered in a manner of fact way that belies the great mind behind it. Very typical of him.
 
We his fellow forum members are blessed by him being on this forum.
 
Thank you Dave.    

I'm with you there, John, 100%.
 
If I see Brundlefly has posted, I always make a point of reading his posts.  I enjoy his calm, knowledgeable and, as you say, unassuming manner.
 

Glad to hear it, Dick. My guess would be that this issue is interface driver-specific. I'm curious whether another suggestion made in the other  thread applies in your case. This has solved other interface-specific issue for me in the past:
 
"If I stop the recording by pressing R on the keyboard and then pressing the spacebar to stop playback then my recordings are fine"
 

... lost and gone forever, oh m' darlin', Clementine Recording.
