I've been trying to play the Island Life mod for Arma 2 and I keep getting this message when I try to log into a server and then I get disconnected. I have tried re-installing both Arma 2 and Arma 2 OA and it didn't help. I am using the steam version and everything appears to be installed correctly. I may be missing something as I am new to this so and advice would help. Thanks!
