Sony Vegas "error exception" and crashing

[crystalsc.livejournal.com]

I feel like I could cry.
I've suddenly started getting the "an exception has occurred" error messages on my project and it keeps shutting down Vegas. I've "save as" and renamed the project but it is still happening.
I can't even work on the video for 10 minutes. If I lose this video, I'll be heartbroken as I've already put a lot of work into it and I'll never be able to duplicate it.

Anyone have any suggestions?

That's a good suggestion! Thanks! I'll try that.

(One of my vidding friends told me that it tends to happen on projects that have a lot of masking)
