Every character show up as a blonde male hume

[Eriphyle]

As the title says, every character show up as a blonde male hume with a huge sword, including mine, who is supposed to be a brunette mithra (the bug occurs on my other character too).
When I restart the game, it's all fine on the character seleciton screen and sometimes after logging in, for a couple of minutes.

Is there a solution for this? I downloaded and updated the game via steam 2 days ago. Using Windows 7 and my hardware and internet connection should be sufficient for running the game.
