I've never had an issue before opening files on Sony Vegas, I normally just hit Open, go into the folder select the file and hit Ok. However, when I try to open one of my files which is in .AVI format just like the rest of my files, I go to select that file, and Vegas freezes on me. It opens every other file, just not that one. Any idea why? Or what I can do to let it open the file for editing?
