Hey DarkXess, thanks for the tips.
Problem is those ca and Expansion I got from the two launchers I tried.
Also since I'll be playing both SP and MP, I would really like to be able to use profiles, hence a launcher.
I'll give your cmd line a try anyway.
The one you suggested didn't work.
Same missing file error.
Reviving my old post because I think I found what caused my problems.
Most launchers create a path string without the last slash "\".
I think this is what is causing the issues here, as the Steam client produces a path string with this last slash.
It's just a theory because when launching OA via Steam, a command prompt is opened and closed in half a second, I once captured (with a print screen) most of it, but not all of it.
And the only difference I found was that. But I may be wrong.
