Problem with SV9

[huddy4chris]

i just started working at a new video, using Sony Vegas Pro 9 and while it was going ok, a message came up that said that "An Exception has occured" and closed it. Now, ever since then, I'm trying to open the project again, and the same message always appears and doesn't allow it to open. Does anyone know how I can solve this?

This is the message:

It's been a while, but I think that may mean you're using a file type that Vegas doesn't support. (I used to get similar error messages, and that was always the cause.) Vegas might load a file type just fine initially, but if it isn't one they officially support, it can sometimes crash the project.
