It won't budge, same error. But I didn't mention something first: I owned ARMA II and OA (Stand Alone). I combined them by using the Addons folder of ARMAII as a mod. No startup error, but it's possible this caused the problem. The only thing I'm confused is how the hell rki_base is involved in such, since my ARMA II is mod-free. It's all vanilla. Any more idea guys? TIA.
