I just bought Sony Vegas Movie Studio 17. When I save my project, close the program and open it again to continue to editing, my subclips always are changed for another part of the footage I don't want (all of them are substituted by the first portion of the movie, always). The program are not saving my subclips. I create them in the trimmer, I rename them correctly, and I dont know what else I need to do in order to have my sublips back again and saved the way I edit them. I tried several times and lost a lot of wotk. Very frustrationg. :-(
