I had to look that up and it appears I installed mine as administrator but up to 5 minutes ago I was having no problems.
Search for accounts in windows search. Click on email and accounts and then your info.
I have no idea why they changed this to not being able to instal as administrator. Most people who have their own pcs are the administrators. I have no idea how to change to non administrator and I don't want to mess around with this function. Well actually I know why they might have changed this but they screwed the main group of people who play at home for the few who play on work pcs who did not have administrator access and had complained about this.
I had been playing the game fine for about 5 hours (except for some display issues in an adventure about 3 hours ago) and then the game became unresponsive and I had to relog and when I did it asked me to download the game again.
