Well I had the same issues of waiting for 30-45 minutes apiece trying to get passed the initial TUT loading screen. I just kept restarting my game multiple times waiting and trying again. This was last night and seemed damn impossible to get through.
I tried again this morning expecting the same ordeal, and to my surprze it loaded for about 3 minutes and i was in. And played a good 2 hours straight with no issues. Im assuming it all depends on time of day how many servers are freed up etc (assume the best times to play are when school and work, and of course after young folks bed time). I hope you get through and just keep at it you'll get in eventually. I wasnt able to for the first few days at all.
