Has anyone managed to fix this problem yet?

Thanks for the heads up.

I also tried it but as with Joepino, it did not work.

Yeah I bought the game from steam, I have also sent Dwarden a PM regarding the issue.

I have ran both steam and ARMA as admin, neither worked.

I made the thread because I have looked in the others and none of the solutions worked, I have also contacted Placebo but am yet to get a response.

Bump, still not working.

A few days ago I started to get this problem, I would try to join a server of DayZ for example, get into the lobby and then after about 20 seconds get an error message saying "Bad CD Key". Now I thought this would be a temporary problem, so I went and played on PR but I got the same error there, as with OA multiplayer matches as well. I have tried joining regular ARMA 2 matches and I can do that, so it seems to be a problem with OA, but I have looked for a solution for about two days now, and everything I have tried has failed to get it working again. Please help if you can.
