Not if he deleted parts of the waves installation ;) still a reinstall of the waves plugs should have worked. Please Summit a crash dump. Let me know which waves plug and version it is. We have the full suite here and they work fine.

Maybe we could program it to delete the rest? ;)

Weird. Okay. After rechecking the box, it's no longer bombing out. I guess the reinstall worked after all.

 As soon as I unchecked the "Replace VST2 Plug-ins When Opening Projects" box, I was able to load it fine.
 

Where is this check box located?
 
EDIT:  Nevermind. Found it.

Solved: Unchecking the "Replace VST2 Plug-ins When Opening Projects" box solved my problem.

I had a similar issue, the very first project I opened caused X3 to crash.  It opened fine in X2.  I used safe mode to open it, not allowing any suspect plugs to load and it opened OK.  One of the things I did not allow was old Melodyne studio plugs.
 
Could the fact that I had old Melodyne instances in the project cause X3 to crash?  X3 seems to have integrated my copy of Melodyne studio seamlessly, and it's running fine in the project now.
 
I did send the crash dump files to CW, so hopefully they will be able to figure out what's going on.
