Arma Arma 2 and Dayz mod

[Robert Picard 0]

I have purchased Arma, Arma 2, Dayz Mod, early access beta i have not been able to play for years and i changed my computer and even my early access is blanked out and I cant seem to play with all three games and I am not a computer technician so I have no idea how to combine the data to play Someone please assist me so I might play I think I proved myself more then interested and right now I feel like a chump who was robbed of the cost of all four games.

DayZ doesn't require any other games to play.

What error(s) are you getting, or what are you trying to do that isn't working?
