Hi, I hope someone can help me this problem.

I recently installed premiere pro 7 on my computer, and everything was working fine but recently, whenever i try to preview the final video, a message comes up saying that "Adobe Premiere Pro has encountered a serious error and needs to shut down". As well as shutting down the programme it also shuts down my computer. I don't know why this is happening as it used to work fine before.

I also have the same problem with Vegas 4.0. Again, it used to play video fine, but now (for some unknown reason) it won't play any video. (Although it doesn't shut down the programme or the computer).

If anyone could help, i would be most grateful.
