I am pretty sure I was switching from a fim to a fbuc (composed of fims), but I am not positive. These are the only two types of files I have, so if not that, then it was a fbuc to fim switch, or fim to fim, or fbuc to fbuc (sorry I can't be more helpful). There were 20 files loaded (3 fbucs and 17 fim), so would that be an issue?
