Cheat detected

hi
I bought original MW2, i have been playing it since yesterday, when the console showed me the error called : cheat detected.
I dont remember which hax did it, but i use wallhacks and game stats mods.
What can i do for plaing back on the internet with my and other friends ?
Thanks

U used wh? and a game stats mods? obviously = a ban.
and p.s. we dont care if u got banned. Thers nothing we can do about it.

and there is no way to unlock it ? I use only level mod, but my stupid cousin downloaded the wallhack, and the day after i showed this fucking error ....

so you used hacks
so you got banned
so that sucks
go play alteriw
