Gonna ask a few troubleshooting questions... not that I'll be able to help but might give a clearer picture.
Do you own the CA2A or just the PC2A?
Is this occurring on all your projects (ones with and without PC2A/CA2A)?
If you own both does there seem to be a difference in the problem between projects that use or originally used the PC version (PC2A) of the VST version (CA2A)?
Have you tried to open earlier versions of the project (that still incorporate the plugin)? What is the result?
If this is only happening on one specific project then obviously the immediate conclusion would be that somehow that project has been corrupted and I'd try reverting to an earlier working version and rebuilding if possible (you can just yank any new recordings/waves out of the audio folder for the project).
You could aslo try opening the project in Safe Mode and disabling the PC/CA2A (or any other plugs that may be the issue) to see if that corrects the problem. Then maybe try reinserting them as needed (which would mean having to redo you settings but at least the project might be salvaged). I'd probably do a Save As on the project before fiddling around too much. Might want to do a back up in another location to send to tech support too.
Feel free to ignore all that as I am not a tech. I do not want to send you on a wild goose chase but those are just some things I might check out.
Cheers.
