Does Anyone Know Why This Happens?

Well basically whenever I try and go on a custom map; e.g Namalsk, Panthera, Taviana I try and go through just regular Arma II: OA and it gives me a ibr_panthera.2 or namalsk or w/e error, but when i launch through commander it doesnt, anyone know a fix?

I'm assuming it has something to do with the launch parameters. I never figured out how to do it. I just get the IP of the non-Chernarus server and use remote connect.
