Soundtrack Pro 9.1.6 - Uncaught System Exception (10.7.2)

Soundtrack Pro is no longer loading past the startup screen for me, and when I launch it via the raw application in its MacOS folder, terminal gives me this:

2012-01-11 19:22:21.725 Soundtrack Pro[12860:2903] .scriptSuite warning for attribute 'script_xml' of class 'MultitrackDocument' in suite 'SoundtrackSuite': 'NSData' is not a valid type name.

I thought it might have something to do with it trying to open the last project, so I tried reopening another project, and that didn't work. I've also trashed the preference file, which also didn't work.

I've already reinstalled twice, and I'm not anxious to just try it again as I've already had to fix Logic Pro in Lion by replacing ProKit and BrowserKit frameworks with earlier versions. Logic works now, and it's just Soundtrack Pro, Compressor and DVD Studio Pro that don't work (not too concerned about Compressor & DVD studio though).

There are an unfortunate number of issues with these pro apps and Lion, and I unfortunately don't have the option of going back to Snow Leopard, but I would if I had the time.
