Emu XL-7 & MP-7 User's Group

I accidentally started saving new sequences downloaded from the net 
(.mid's) onto my XL-7 without giving bank assignments.  So it started 
saving over the original presets in the active memory, then the PC and 
XL-7 combo gave an error and stopped the process before the first 
saves even completed.  Right now it gets stuck on the "XL-7 Command 
Station Ver 2.0" screen and the only button that lights up is the tap 
button, which flashes three times then does nothing.  Is there a 
button combo you press to have the unit completely reinitialize 
presets from the ROM's?  By the way, I tried reinstalling the OS and 
while it worked it didn't solve this problem.  Thanks!
