I'm guessing you're using the survival hack, and if I'm right the survival hack was just recently detected; so you might be receiving a global ban momentarily.

If you are talking about the survival hack, it's detected, which is why DayZ crashes. Don't use it until a newer version is posted unless you want to get banned.
