Error Message in Pro Tools

Are you saying that there is an error in Pro Tools when it tries to open the AAF created by X2Pro? If so, then it's unlikely that the issue is with X2Pro. Have you tried opening the AAF with Pro Tools on a different machine?

When I tried to create an AAF file with the X2Pro plugin a few months ago I got an error and was sent a beta version (2.5) which worked perfectly. My beta version expired and I then bought the upgraded x2pro from the apple store. Now my post sound guy is getting a "because an unexpected error has occurred" message half way through rebuilding the audio timeline and it aborts. I have to assume it is on my end because it worked perfectly with the beta version. Is there any way to fix this? Or just get my hands on version 2.5? Thank you so much!
