Hi I have this problem about dayz. I know these "ca" errors have been a problem for a lot of people. I get Ca_signs2 every time I try to launch dayz. I've fresh uninstalled and reinstalled with all up to date patches. I've tried to coyp the AddOns folder from arma 2 but still no luck. I've played dayz in the past and it worked fine but this time it really annoying me. Any help will be great.
