Greetings!
My problem ls, that no image shows at the character-bulding-screen. Just ab blurry red question mark. I googeld the bug, but the only the solution I found was to run the game as adminstrator - which I did.
But It didn't help.
So, any idea how to fix this?

It feels like the files relative to the 3d models can't be accessed.
You could try uninstalling and reinstalling.
Redownloading the installer might also help (circumstantial).

First: many thanks for the help!
Got it fixed now. H3SHA was right - a re-install was necessary.
But there is an addition! See, i'm from Germany and my username in Win7 uses one of the typical nouns (ü).
It seems PoE can not find the data when there is an ü,ö or ä in the installationpath.

Second: You should install the game in english and later choose your language prefence. It seems choosing another language than english for installation can cause problems.
But that's just a theory.

So, many thanks for the help and I hope you all have fun with the game!
