Making the move from Final Cut and was happily editing along in Premier today when all of a sudden all the media in my project folders diappeared. The folders were still there but the media was gone. The media on the timeline was still there as well. After shutting down PP and restarting it the media was all back but this has me a bit worried. Is this something that can just happen in PP and I should stop worrying? Or is this something I should be really concerned about.
