Vegas Pro stopped working after installing update. It goes through the motions but the window never opens. I've tried uninstalling and reinstalling same results.

VERY URGENT: Same problem here. I can't edit anything any more now. Restarting the computer or even re-installing the whole program doesn't fix anything. I don't even see the Vegas process running in the background. It just starts like it will load, then the starting windows vanishes and nothing.
