When it says connecting to account server, that got to be a problem at cryptic's homapage ore somthing. not an isue with loading a game. like cryptic have deactivated lots of accounts so the server will not crash ore somthing.
WHen you go into launcher, BEFORE YOU HIT ENGAGE, go to Options and make sure your Proxy is setup to "NONE" dont pick US or EU. I had it on US for the longest time, and when i switched to NONE, smooth sailing. Connections all the time!
