Spalding

Hello, I can't seem to log into the server. I'm new to this so I'm hoping someone can point me in the right direction. Al mods are updated as of today. I got the terrain mod (@CUP Terrains - Core, @CUP Terrains - Maps) by subscribing to the CUP terrains in Steam. I keep getting this message after logging into the server: "Files "C:Program Files(x86)\steamapps\common\Arma 3\@CUP Terrains - Maps\addons\cup_terrains_maps_afgan.pbo" "C:Program Files(x86)\steamapps\common\Arma 3\@CUP Terrains - Maps\addons\cup_terrains_maps_afgan_c.pbo" "C:Program Files(x86)\steamapps\common\Arma 3\@CUP Terrains - Maps\addons\cup_terrains_maps_bohemia.pbo" "C:Program Files(x86)\steamapps\common\Arma 3\@CUP Terrains - Maps\addons\cup_terrains_maps_bohemia_c.pbo" "C:Program Files(x86)\steamapps\common\Arma 3\@CUP Terrains - Maps\addons\cup_terrains_maps_bootcamp_acr.pbo" "C:Program Files(x86)\steamapps\common\Arma 3\@CUP Terrains - Maps\addons\cup_terrains_maps_bootcamp_acr_c.pbo" ...are not signed by a key on this server.
