If you installed VP13, then you'd need a serial number otherwise you are in trial mode and perhaps not all things work the same as in the unlocked version.
it looks like I have version 13 build 879 64-bit, I remember doing an update to fix some things and it could have been the pro update instead of movie studio. That might explain this. Anyway to roll back the update?
I just found vegas pro version 13.0 (64 bit) 13.0.10 in my control panel. It was download May 22. That is when this issue started. I bet that is the problem. I will try and uninstall it and see if that fixes this issue. Thanks for all your help with this matter.
