This also affects me. The patcher does not appear to try to patch the game (i.e.i it's missing the progress bar and associated buttons at the bottom). When I try to login I get a error dialog prompting me to enter what I was doing at the time the error occurred. I tried the IE suggestions above, but no dice.
I just want to get back into the game....I've been away for a long time and I want to see what has improved. I want to believe laying down all that money before the game launched was worth it. To run into this is frankly, disheartening.
