Freezing and unfreezing track resets synth?

Hi, newbie user here! I recently froze a Rapture simple instrument synth track to save some CPU cycles. Now that I unfroze it, the track is silent, because the instance of rapture on this track now has no program loaded. It will be hard for me to find which program I used, but at least it was a preset... Is this behavior expected? Is there any way to retrieve the program, except by trial and error?
 
 

Thanks for stopping by. So I take it this is not expected behavior.
I got Rapture quite recently (from the CM 200 anniversary issue download) and haven't updated it afer getting it. I am working on Sonar X3 32 bit currently (steam distribution). I migrated this project from Music Creator 6 touch to Sonar a week or two ago, but I believe the current rapture program and notes were recorded after that. I definitely froze and unthawed it in X3. I don't think X3 was updated while doing this project, but I can't be sure since on steam updates are applied automatically, and I may have overlooked it updating.
 
Anyway, I could solve the immediate problem as I was able to find a backup, where I could look up the name of the Rapture program in question. Still, I am now worried about using the freeze function, so clarification would still be much appreaciated.  
 
Edit: added signature for system info

Your back up is located in the folder you backed it up to. just look there and you will find it.
 
And no, this is not expected behavior. I've been freezing and unfreezing in sonar for over 10 years and i never lost a setting or preset. I always get the same exact settings i had right before i froze it. This leads me to believe that you changed something before or after you froze the synth.

Yep, I've seen this, but only in a very specific situation. I had a series of projects that I had started in Sonar 7 - while working on the arrangements, I froze some soft-synths to free up resources temporarily as I was futzing with other bits. When I upgraded to 8.3 and re-opened those projects, anything that had been frozen while working in v7 lost its settings when unfrozen in 8. By the time I realized what was going on, I had already written over the earlier backups. Your experience of creating the sound in one program and then porting to X3 sounds like the same problem.
 
So now, even though I have *never* had this problem in any other context, I always always ALWAYS export the synth's preset before freezing. I'm also paranoid enough that, before UNfreezing something, I copy the frozen .wav to a new track in case the preset doesn't come back. Hasn't happened, but a little paranoia can be good for you sometimes.
