Game crashes when trying to enter Ruins of Kingsmarch

I traveled south but now that I have reached Kingsmarch the following happens:

Go to world map select Ruins of Kingsmarch Waypoint
Klick Travers
Portals open
Go into Portal
Game crashes during loadingscreen

If you could be so kind and fix this :D

Something similar happens to me. Except I don't crash, I am just stuck in a loading screen. I notice that the number in the small Debug window next to the "Shader: " does not decrease. Once after like 10 minutes I managed to enter, but everything was black and after changing a setting in the options I got a "Deadlock detected" Error and the game crashed.
