I have had Vegas Movie Studio Platinum 8.0 for over a year now and recently, within the last few months it will not open. I have tried everything from fragmenting my hard drive to installing it again after uninstalling it. When I go to open the program it says that a problem has occured that will not allow the program to continue running. When it says this it is always on the initiating phase of "creating file I/O manager" - not sure if that helps. I wasn't worrying about it too much when it first occured but of course now that I really need it I can't seem to fix the problem. If anyone has any ideas I would greatly appreciate them!! Thanks!
