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

Hello,
 
Today i've exerienced my first Problem with my mp-7.
 
All of a sudden a few presets of my patterns resetted themselves to
Preset 000 0 (png:Transformed). This mainly happened to the bassdrums of
my songs, but also some other instruments were affected.
 
Of course it'd be a little annoying (if not impossible) to search
through all presets, to find the right ones again for almost every song.
 
I currently only have the original ROM installed, so the error couldn't
come from i.e. a missing ROM or so..
 
Did this happen to someone else before?
 
cheers Chris
