“What build of Vegas are you running? You could try Ctlr+Shift on firing up Vegas to reset to Factory default.”
Build?I’m pretty sure its 563 if that’s what you mean.
” Is it possible that formatting the disc has required you to register your copy of Vegas? Maybe you’ve used up your Serials?”
No it didn’t and I tried to re-install once and try to run the trial version..and same problem came up.
