So, I'm quite new to the game and basically when im trying to connect to a server in DayZ it will reach a completely black screen with the word "Loading" then freeze, and my mouse cursor will disappear completely and in order to get it back i have to ctrl + alt + delete and start a task manager and close DayZ, i have no idea how to overcome this problem so im in search of friendly responses with suggestions of how i could fix this. Thanks.
