Account Password on client

For some reason i cannot log into crossfire CLIENT, whenever i put my correct username and password it tells me wrong username and password. iv tried changing my password, iv tried re downloading client. No matter what i do i cant log in, i doubt im banned or anything i dont use any hacks or background programs when running crossfire and i dont have any tickets against me. i can log into the website and forums no problem. if anyone has had this happen and knows a work around or whats happened to my account please let me know. i just want to play some cf.
