cannot load dll error! help

i need help trying to reinstall combat arms. i ran as administrator and it said cannot load dll. that is all it said there was no names just cannot load dll. i uninstalled combat arms earlier because it kept crashing so i was going to reinstall it but now this problem arose. any help would be appreciated

Are you having trouble installing it or is it installed and your having trouble playing?

i fixed this error by doing a system restore and i installed combat arms but now combat arms closes and says connection to server ended. is anybody else having the same problem
