I've just started using Sony Vegas Platinum 9.0, and when I'm importing video, it comes up with an error, ("An Exception Has Occurred") and upon clicking ok, which is the only option, the program closes down. The error code is as follows:

The video files are simply mpeg files that i have ripped from a dvd. I have tried several different files, and once I managed to import one of the files (after I had been given this message twice before), but that's it.

Please help me, I don't want to have to use Windows Movie Maker my entire life!

i have the exact same problem and so does one of my friends. whenever i try to import a video file from my sony camera, it tells me the same thing, and hen when i click ok it shuts down. I sent this to a tech at sony and he instructed me on how to repair a few files that were in the program and i did but it still wasent working. i replyed what it said and then i hade to do over 3 pages of stuff to "fix" the problem, and i spent more than 3 hours doing all of the steps, and when it was finally done it still didnt work. Im lost.
