I have a multitrack that I want to use to round out a live performance of a song but when I open the multitrack file i get the message "Some of the media files(such as samples) used by this set could not be loaded." If I go into File Manager and show what it's missing it doesn't show any missing file?? Also, if I go to the track I am trying to get working in the file location it works... Under sample it says file is offline but I can't press any of the edit save rev. buttons as they are greyed out... Any ideas would help a lot!
