I think I had the same problem. At the time when error occurs, you get 2 processes; exit that one for deactivation, and continue with that other one (don't cancel deinstallation). Sorry for this messed up explanation, but I hope you'll understand it.
btw, I was on 5th activation out of 5 when that happened, and I couldn't deactivate when uninstalling... but when I reinstalled it, it was already activated lol, so I didn't loose that activation for some reason.
