I recently installed Metro 2033 and can't launch it because it says PhysXLoader.dll file is missing. I try to get the latest version of it from Nvidia's site but the program says that my version is more up to date so it doesn't install. So I'm kinda at a loss here. I'm trying this on my laptop and it has a Radeon Mobility HD 3650. It should have all driver's up to date and everything. Anyone that can help me I would appreciate it very much.
