When i open the server this message comes up and where the adress usually is it just says the same message. Last time when nothing showed up it was a virus though this time i did a scan and it's not that. Also, i tried deleting externulurl but it didn't work.
one more thing, does updating mcdzienny make you lose all your data? Someone told me that, I'm not sure if it's true but i'm not willing to take the risk.
