Anyone?

A little update: I've tried to load the operating system again (new download, new disk) but now i can't even load the operating system (or styles) from the floppydrive. All i get is a error message (program flash corrupted, write program on flash E0).

It seams that the keyboard isn't able to acces the flash memory, which is were i guess the factory styles are located? I've opened the keyboard again and neither me or my friend can se anything that seams out of the ordinary. All connections are clean and fastened as they should. Nothing is damaged in any way.. I've tried to reset the keyboard in every way i can, i even formated the hard drive. But nothing works..

Is there a way to reset the keyboard at startup? Is there anyone on the forum who knows anything about the flash memory, is there a separate memory for the sounds and are the factory styles located in the same memory as the operating system and user settings? Any help would be appreciated.
