X2Pro Crashing on OS X 10.7 (Lion)

Version 3 of X2Pro is not compatible with OS X 10.6 or 10.7 due to some of the new features that it uses not being available on those OS versions.

If you are stuck on OS X 10.6 or 10.7, then v2.5 is the last version that will work for you. I'll email you directly with further details.

Hello there,

As the many other people on the site - I am in dire straights right now and have a deadline for a corporate video for tomorrow at noon.

I'm running Final Cut Pro X - Version 10.0.3 and I've just purchased the X2Pro software to convert an .XML file to an .AAF for my audio engineer to use in Pro Tools.

The .XML file I'm getting after export is 66KB (these are 2 minute long videos)

When I plug the .XML file into the converter and click "Start" - the X2Pro software completely shuts down and an error message comes up to either close or Reopen.

Can you please help me?

Attached is the .XML file

Thank you so much

Kyle
