I have the same problem with the trial version of Vegas Movie Studio Platinum 8.0. It also happens with Movie Maker, apparently with any video editor software. I can tell that when it’s trying to initialize the audio engine it get stocked and the message comes up: Vegas Movie Studio Platinum has encountered a problem and needs to close We are sorry for the inconvenience. I saw you found the solution, but how can I find which program is interfering with my Vegas’ Software??? Please help…!!!
