I have not tried to delete dayz from the documents, what I have tried is to delete dayz from steam several times and it has not been solved, I have also checked that the dayz folders have the permissions and I think that is fine but it has not been solved the problem, I know several people with the same problem and none of us have been able to solve it, within dayz I have around 600 hours and it has never happened to me but one day suddenly the problem started and since then it hasn't stopped
