I've tried everything.

Hello, Brim here.

Here are a few bits of information first before we start- I have the correct and brought version of ArmA 2 OA, and the demo version of ArmA 2 classic from the ArmA 2 website. I have them both on steam, the demo was added as a non-steam product.

Basically, I've been trying to fix this problem for a long, long time now. Maybe a week so I'm finally posting here because I wanted to refrain from being a pest.

Here we go- Every time I try and launch Arma two combined operations it tells me that I don't have a registered version of both the games. And then, it will continue to launch it but the DayZ server will say "Missing Config.Bin/model_wall/shed.something" and it varies to different models and folders every time I try. It also keeps saying from time to time "DayZ.anim requires CA_Dubbing_Counterattack." and continues to launch anyway.

I really don't know what's going on, I've re-installed both games twice, re-installed battleye or what ever its called twice. Looked all over the net (though admittedly not through all the hundreds of these posts in the forum lol) I've patched dayz and my arma games up to date. Tried re-installing dayz manually. I'm not sure if there is a website I have to go to these days to register my game of Operation arrow head but it never used to be a problem for me. Nor was it a problem to use the free version of arma 2, though I did dl it from steam back in the day.

I'm wondering if you need to buy both copies of each game now, instead of having OA and dling a pirate or a free demo type.

I would try getting buying the full versions of everything.
