I have never heard of Luxmark, Imma try that next. I also tried everything you said, except Luxmark download.
I also gone to the PC shop yesterday and they told me they tried installing another Windows 7 OS and testing vegas out on that, and they told me that Sony needs to update their drivers or something like that, I kinda forgot how they said it, but that’s the gist of it I think.
But I got it working when I gone into the Device Manager and disabled my grahpics card, then I open up Vegas Pro, and then turn on my grahpics card, this time it didnt close on me. Btw, im using a NIVIDA Geforece GTX 970.
If possible I rather have Vegas working without going through that process though.
