Thanks for the replies guys. The extension is already .veg, but the properties say its a .bak file. The icon is also different to a veg file.
I have tried opening the .bak with Vegas and as the extension is already.veg, changing it makes no difference : (
Derm, Windows is hiding the "real" extension. You need to go into Windows and turn that off. BAK files are typically something like myfile.veg.bak so you're seeing the .veg but Windows is hiding the .bak.
Mike, Jetdv, everybody, huge thanks : )
4 hours of work rescued
It doesn't bother me so much now that we have no Olympic medals. I feel like I've just won a prize : )
Mike, I must thank you. You saved a whole day worth of work for me and I thought it was hopeless. 16 years in the future, your advice helped a lonely kid make something great.
