Just purchased Elsweyr upgrade through Microsoft and now can't launch Tamriel Elderscrolls online game - it is asking me to re-install game from the purchased disk? Have I lost all of my Elder scrolls game save and am I ok to re-install the game as requested (along with 70GB of updates???). I also have upgrades for Morrwind and Summerset installed - why has the purchased upgrade wiped my game data for my original purchase?
