I just want to add a few things to my previous comments, hoping that these can help other VA owners.
I have tried to load OS 2.0 for VA 76 on my VA 7 and this time I used a pen (instead of my finger) to calibrate the touchscreen; everything went fine and the keyboard powered on as usual. When I went on to check my user programs, however, all the split points and the octave transpositions were messed up. That was due, I guess, to the fact that the OS was thinking that I had a 76 note keyboard instead of a 61 notes one.
So I re-loaded OS 2.0 for VA 7 and everything went fine.
When I upgraded to OS 2.0 I was told that I could not do it myself because they had to replace some internal chip but that's not true. You can do the upgrade yourselves and the only things that you will be required to do are to calibrate the pitch bend and the touch screen after rebooting.
The only reason I can see for upgrading at an authorized center is the new Zip disk with about 1000 user programs; I had to pay for the upgrade (about 40 Euros or 35 dollars, more or less) but I am told that in some countries (like UK) it's completely free.
Enjoy your VA.
Andrea
