Floh and Michael,
Thank you for the suggestions. Here’s an update: I can export a file for After Effects, but I cannot export a regular XML file. When I go to File>Export>XML it always results in Media 100 quitting and disappearing with no error message whatsoever.
I’ve repaired permissions, all the usual voodoo, created new projects/programs, etc., all with the same effect. It’s the strangest thing I’ve ever seen in Media 100.
Fortunately, I don’t really need to export “regular” XML for Final Cut, since I hardly ever use it. Since the After Effects export works, I’m okay for now. It’s just very strange that it would vanish with no error message.
And… even with this little quirk, I’d still rather use Media 100 than anything else.
