i dont know if this type of email is going to get though but, im trying to play DayZ for the first time. and im not into computer games so much so its hard to download or install DayZ. so hopefully someone can help me. ive downloaded i think everything i need to play even the playwithsix download. but everytime i try to join a server the messege "it appears there are no installed games detected to launch you can configure game paths in the game section settings" now ive looked through the playwithsix website, my computer settings, and the server browser and i cant find any game sections at all. is there any help anyone can give me to help me get past this so i can start playing DayZ?
