I'm trying to edit a video and this is all I get whenever I try to drop the video in Sony Vegas 9 "none of the files can be dropped in sony vegas 9". A few weeks ago, the program was working perfectly fine now all of sudden I can't drop a damn thing into the program!! I tryed the RZ Converter, no luck. I can't even drop mp3's, I have to convert them to .wav file. Can someone please help me?
