Guild Wars 2

So after the patch, I went straight to brisbane to enter the new map.
I headed to the south west corner, but short before I explored the new area with the portal there, the game froze. Nothing worked, so I needed to close it.

Since then, whenever I click “play” with one of my chars (not only the one in Brisbane) in the char selection screen, the map loading screen loads and loads and loads and freezes after some time, too.

I feel unable to log in on anyone of my chars.
I’m hoping that something can be done about it, I’m so eager to explore Dry Top :/

edit: I’ve installed a second copy of the game on another hard drive and that one works fine. Looks like something with the patch downloading went wrong, I’ll reinstall and see if it’ll help.
