Hello, yesterday I played Call of Duty 4 online... for the first time... and a lot of servers are hacked.... well, I played a cage match.... and right after it started (the map was shipment) I killed the (I think) Host of the Server and got something like -2000000 EXP!.... I wrote him a message and told him I want my old rank back.... Now I have a score from about the named number of EXP..... and I can't join another game any more... it is indicated that the there are no players online... I don't know what to do....? And I 'm very feared of getting banned for mods or something like that even though I'm innocent!.... I need help please fast.... My Gamertag is "Kajo Crutelos"... and the Gamertag of the guy i played with is either "[HOST]iSaaaaaaaam x" or just "iSaaaaaaaam x"..... please I need your help what to do.. I want to have my old rank back (it was something like level 20 or 21.....) and I don't want to have a ban!
