Actually you don't. The mistake was on my end. I downloaded the russian weapons pack and now the ace version works. I must have overlooked it when downloading from armaholic.
Exactly. I press ok and nothing happens, I'm still at the scenario select screen. If I try again, I get the same error then once again, hitting ok does nothing.
I can't seem to play this mission because every time I go to load it up I get an error stating 'No player was selected!' then nothing happens. Any idea why this is happening and how I can fix it?
