Vegas 8 crashes during render with Cineform files
 

I am trying to render a short trailer in Vegas 8, but it keeps crashing.
The files are Cineform 720 30P Avi files. Vegas crashes when ever I try to generate any file, MPEG, AVI, WMV, QT, etc.

Here is the referenced crash code from Vegas.

I have no idea what any of this means.
Anyone have any ideas?

R u on 64bit or 32bit? What OS? Any plugins?

Sean I am working on the 32 bit version of XP Professional, on a MAC Pro 2.66 Quad core running on Bootcamp.

Just of note, I was having another issue with Cineform NEOHD crashing on me from time to time while creating files. Cineform emailed me an updated version to try out, which I didn't try installing until last night. The update seems to have fixed my crashing problems in both NEOHD and Vegas 7/8.

So currently all is well.
