Bad Serial Number given in Setup

[megabob711 0]

I've had this game for about a month, everything was working fine, but when I went to join a server last night I got this error message: Bad Serial Number given in Setup

I tried joining different servers, and all of them gave me this error. I checked that everything was up to date, ran steam as admin, and restarted my computer, but nothing worked. Can anyone help me? I really want to keep playing this game :(

You need to:

1. Uninstall arma 2 and OA

2. Reinstall Both games

3. Run both of them (not at the same time)

4. Patch for 1.60 then 1.62 then run the newest beta patch

5. Hopefully it works, it worked for my friend

Uninstalling it should be the last thing you do to fix it, not the first. Edited September 21, 2012 by IIxSubmarinex

Uninstalled both of them, still gives me the same message. Any ideas?
