Hi Raze
ok, downloaded PhysX from nvidia directly. uninstalled and installed it. Rebooted. Didnt work. Actually I do not understand the instructions for the second help 100% so I downloaded the file from your link and copied the file to the windows folder system32 as mentioned. Didnt work, the message still shows up. The game works now and also loads when changing the setting, but once in a while it crashed (or rather freezes)...
