Tried Google, but things get fuzzy. So, thank you for your help. When I press the 'Play' button on the Arma 3 launcher, it gives a 'CCG_Client requires excile_client' to run Then shuts down. I've reloaded/updated mods and even unintalled Arma and Steam (I'm a noob at all this) The biggest confusion I have is the mods are in Steam folder and not Arma? And all numbered? I'm drowning. Any help would be awesome. thank you, Grumps
