I'm going to assume by switching your key to a valid key. Maybe you ran a keystealer that stole your key and switched it to an invalid one. Unless if your talking about "Bad Serial Given at Startup"

Either switch keys or check if you really spelled it right.A friend of mine had the same problem but he coulnd't fix it.

You can type in regedit in the start menu and find your Arma 2 OA key and then delete it from regedit and then re run arma 2 oa from steam. Steam will give you back the original key you had because it sees that you are playing and gives you your bought key. I believe you want to follow this path to find the key
HKEY_CURRENT_USER > Software > Bohemia Interactive > and now i think, if i remember right you go to SigningKey... I could be wrong. If so, just look around in regedit for your key. Thats what i did at one point.
