The problems seemed to have been resolved. I reloaded the projects from back ups that I had made before the crash and now everything is working correctly. Not sure what the problem was but backing my work up seems to have saved the day.

Sonar Platinum latest Lexington + latest Z3TA+2 version: replace vst2 box checked

New project - adding z3ta+ 2 (vst2) - saving - close Sonar. Open Sonar - loading saved project - error uncompress saved program.

New project - adding z3ta+ 2 (VST3) - saving - close Sonar. Open Sonar - loading saved project - everything fine.

vst2 to vst3 migration problem, vst2 .dll issue, differences between vst2 and vst3 presets format problem?

When replace vst2 box unchecked project loaded without error (vst2 plugin in project like above).

I have Z3TA+2.2.1 installed but Z3TA still loses the song patch every time I close and reopen the project. What do I do now?

These are very good news.
 
But Z3TA+2.1 doesn't appear in the Command Center Connected Products.
Is it possible to connect it manually to the CCC ?
If I install the demo would my 2.1 Serial Numbers work?
Thank you.

If you've already got Z3TA+ 2.1, 2.2 should have automatically been added to your Command Center. If you don't see it, just drop our Customer Service a line and they'll be able to fix that for you. 

Thank you Jon for the reply,
Yes I have Z3TA +2.1 installed and working since a long time.
Sure, I'll turn to the customer service.
Best,
Sylvain.
 

Update:
Problem solved in no time by Josh (Cakewalk).
 
Just for information, the problem was created in the first place by the fact that Z3TA+2 was registered with an old, non existing anymore, e-mail account.
Best regards,
Sylvain.
 

I am currently still running 2.1 Because 2.2 Doesn't install correctly (Do not even get to select the install dir)
I already have contacted customer service About this but after 2 weeks of waiting still no reply
Only An Email that they received it and will reply as soon as possible :S
