Hi everyone, i have a problem with the Launcher of Amnesia. Some time ago, i have Ati Radeon hd 4670 grapich card and i can play the game in high setting, but now i change the graphic card to ati hd 3450 and the launcher don't respond.

My OS is Windows XP Professional SP3

It's a desktop and i open the hpl.log and i found this:
