Magus try this as a test:
make your crystal
then putt in the MIDDLE OF YOUR CRYSTAL a as whit the texture "origin"
then GROUP it together TO a "Func_rotating" (as you might thit already)
then Properties @
then only turn on the "START ON"
the rest leave it OFF
Then go back to Class info and putt the "smartEdit" button on
Find the Angles and Putt it on "0 0 360" ( x-y-z )
Speed - just.. Turn it to 100/200 or some thing(low turing speed)
-> how higher numbers will get it turn faster!
(as you might already know i guess)
Then save it all and try it as a test..
IF IT IS WORKED ! -> continue your map and PUB it!
HAPPY MAPPING TO YOU (ALL)
