Just today I had the first problem of my 1 month old VA5. Yesterday I played normally my program. Today I powered the VA on and it started with calibration of the stick and the touch screen. After that it displayed a message that "Couldn't write the Eprom memory", and I had lost all my disk links, the Scale tuning memories and ALL the One touch setting, internaln or on disk!!! The registrations where there though. I restarted it and the situation was the same. I quickly restore manually the disk links because I needed them and after another resatart (and several more during the night in order to bring it back functioning normal), I didn't lose the disk links. But the One touch buttons were empty and still are, and if i pressed one of those empty buttons, then I lost all the tones!!! There were empty buttons there as well! They were restored after recalling a registration (no matter which). The one touch button still don't work. Does anyone have an idea how to restore them? It is urgent and I can't sent the keyboard to service since I'm playing 6 nights a week.
