Hi, first of all, thanks for picking up this thread.
In my experience, I never use the rev-x, is the mr extension that causes the problem, because it only crashes the first attempt at loading the large project. Also if I remove the mr´s .dll from the original folders, I get no crashes.
I have problems with Eastwest Play, and also with Eastwest Spaces (reverb), when I load REVerence from cubase in the same project, I loads ok. Also, I don´t have problems with Omnisphere.
I don´t have any UAD cards nor VEpro.
Thanks very much!
