I have a problem at load of a map.

In GCW, I have no problems, only in CW. When I try to load a map, the map goes right to the end of the load sequence... and stays there.

EDIT: I know why now - the new sound LVL I'm using disliked the MTT sounds. I wonder if I missed a sound out. Is that possibly what caused the freeze-up - that it was trying to read a reference file that simply wasn't there?
