I am experiencing the exact same problem now too. I logged out in Thorin's Hall, and now cannot get past the loading screen after character selection.
So now I have a simple question: Why?
Why am I going to pay money for points to a game I cannot play? Why am I going to pay money when it seems the developers don't give a damn about solving the problem after so long.
And it is not a user issue, as nothing has changed on my PC since playing this morning before work. This problem needs to be fixed.
