I tried all of these and still cant get on/ i have error 22.0.-1 am i ban or is it not letting me on for some reason. i couldnt play this game since release. only got to play for like 15 min. HELP!!

i had the same problem,i tried playing on a different acct that has never been played for cod and works fine. then to be sure, after playing for hrs on new name i tried the 1st name and didnt connect to server. I think it might have something to do with people having modded saves on their profile on older cod titles like mw3 and bo1.
