FSEdit help!

Hey all-
Recently I have been getting an "illegal operation" message when trying to open the aircraft list in the fsedit program, was wondering if anyone had any input?? Also I've noticed that I cannot find the new aircraft in fs2k2 that I have added, which may or may not have something to do with it, I'll try playing around with the aircraft.cfg files as that has sometimes helped, but the fsedit thing is still annoying me!
Would appreciate any help!
