I have the same issue. I downloaded the patch, then I logged for a few minutes. Went to log in, got to the character screen and hit enter. Game was flashing between black screen and my monitor.
Only option to get out of that scenario was to ctrl-alt-del. I unistalled and now I am having the same issues. I get to 9544 kb downloaded but then the dl speed goes to 0/0.
I’m having this same problem. I just got a new computer over the weekend and it just freezes after downloading 9544kb.
