When I go into a server running CI I get kicked for modifications/cheats installed with a bunch of numbers and letters after it. I tried reinstalling and play completely stock with no custom crosshair, scope or anything and it still kicks me. When I check my unnamedsoldier.cfg after under cvars this shows up, seta r_glDriver "opengl23s" don't know if that means anything. The only other thing I can think of is its a bad no cd crack, is this possible? Please help. Thanks.
