Bc2000 (for the BCF2000 & BCR2000)

Hi guys, my BCR2000 seems to be having problems where it looks like my EDIT button does 
not function normally anymore...
Now I found the BC MIDI implementation.pdf online and there's a section that describes 
where a button (even the Function buttons) can get different functions...
I was wondering if any of you has a sysex file maybe with which the function buttons are 
restored to their original values.
Reloading firmware upgrades and factory presets does not seem to do the job...

Maybe it's lost at all but actually the edit button seems to be the only thing that does not 
seem to work but this means I can't get in to edit mode for the encoders/buttons and can't 
get into global mode as well...

Any help???

cheers
