textures arent show

Hey Guys,

i hope i´m in the right category. i got 2 little problems:

1st problem:
I´ve always played with 1280x800 (wide) but since yesterday (befor and after the mainteance) it doesnt works anymore. I just can play with 800x600.
I cant change it. In options there stands 12080x800 (wide) but i play in 800x600.

2nd problem:
I can see all textures in Lobby, Storage, Black-Market and so on but not in the game.
I can´t see the statistic and everything else.

Sometime pictures are better than 1000 words:

I tried a lot of things like:

deinstall and download + install the client again.
updated the graphiccard-software
checked my computer on virus and so on.


I dont know any other solution.
I hope u can help me.

If some dude can explain it on german it would be the best. (cuz i am :P)
