Hi, I did a fresh full install of the program using the latest installer from the download link in the registration email. When I go to clean using the "Nvidia" profile alone, the program always crashes. The same thing happened when I tried to clean multiple profiles at once:- "Nvidia", "Nvidia PhysX" and "Aegia PhysX". I was running Vista Business SP2 in safe mode, with the DC.net running with administrator privileges. My specs:- Motherboard: Asus P5Q Pro Sound Card: Auzen X-Fi Prelude CPU: Intel Core 2 Duo E8500 @stock GPU: Nvidia Geforce GTX275 @stock Here is the error that I've been receiving:- Thanks in advance.
