Are you running Steam as an administrator? If not, you sometimes need to for Arma II.

This sometimes happened with me on DayZ. It usually gets fixed if you run the right beta patch install.
However, you dont have/need a beta patch for just Arma2, so I dont know how to fix it for that.

There are 2 fixes I know of with this problem

 1st fix: Launch steam as Administrator

 ---------------------------------

Another problem/fix
If you have tried to download any kind of hack, it would've been a key stealer. In that case you need a new CD key

This certainly NOT.
If you downloaded unsecure files which happen to be a key stealer, your key got replaced with a banned key in your registery making you think that you got banned, so you buy a new key while your old one will be unused so that the stealer can sell your key without getting the in-use error. All you have to do is change it back using a third program (google it) or manually in your register. (Though you have to convert your CD key to HEX first.)

And if this really is the case, Then you will not get the 'Invalid key in setup' error!
If this is the case, you will be fine to get in the game, but given a message: "Global ban #....." when you try to join any server.
