Still having problems with the Black Box

[LittleTom]

Hey guys.

I looked for hours to get Amnesia started and looked in any sites and threads for help.
The problem is whenever i start the launcher and wanna strat the game I get the Black Box error.
I looked at the two main threads for finding some help too.
Now here it comes...
Yesterday i had Windows XP SP3 on my computer and it worked totally fine.
Today i got Windows Vista SP1 with all the updates of graphic cards and etc. and it still won t work.
I decieded to look if my graphic card is up to date and it is!
So my main problem is that i doesn t have and hpl.log file in my main order and i can t put it in here.

Sry for my bad english. I m a german student who is still learning this leanguag.

P.S I got a nvidia geforce 520 graphic card.

Hope somebody could help me.
