Problems with ARMA2:OA mission "Open Season" on OA campaign

[Problems with ARMA2:OA mission "Open Season" on OA campaign]

Whenever I try and load this mission up I get something along the lines of "You cannot play this mission, missing downloadable content ns_mutants, ns_ui, ns_fractions, ns, ns_sounds, ns_modules .... " and a few more. Go to verify game cache, file missing, reacquire, repeats. Help?

Awesome, thank you ^^

And Xtreme servers, or something like that? I didn't buy it directly, I'm one of the ones chipping in.

Ah okay;

Having found that file how would I go about using it to run a server? Unfortunately I'm not very tech-savvy :c

Ah okay, thank you for the prompt response and feedback, I will look into that & move the post if I can.

Apologies if this is a badly placed thread, I'm new to this forum;

Some friends and I bought an ARMA server to play together on and mess around (it's not public, only the few of us who bought it used it), and initally we used it for DayZ, but after playing Wasteland, we think it would be a far better mod for how we play together (I.e. fighting over towns in teams; base building & randomly spawning weapons and vehicles make this interesting). I can't seem to find the mod for download for servers anywhere, is it available to host privately, or is it strictly reserved for the public servers it's currently hosted on? Or is there perhaps a mod you'd better recommend for this?

Thank you.
