I would try re installing it. I have Vegas and it works great for me. Besides it taking a few mins, i have nothing but great things to say about that program.
Is your version of Vegas….10? Ive heard it has problems with older versions such as 7.
Make sure you add xtra tracks for Video and Audio and lay it out with a few xtra.
Probably not much help, but reinstalling things always helps.

If you have any other questions on Sony Vegas let me know. I am a wiz at that program.
Thanks, and appreciate your response.
