magical solution

okay so right now my copy of rtcw is driving me mad

I quit playing yesterday evening and now in the afternoon when i tried to join rTg I get an "invalid_cdkey" message again when I try to join a server

I dont have a cracked version of rtcw and the key should be working, or in fact, has already worked yesterday. I didnt change anything at all in my rtcw folder since I last was on a pub

I basically tried everything I could think of, re-enter the key in the 'rtcwkey' file and save it again, overwrite it, delete it from the folder and manually enter it in rtcw itself and then connect.. restarted the game a thousand times i ran out of options.

Can anyone tell me how in jesus' name im going to get rid of this nonsense? Please halp
