And sorry for my english. I am a potato.

Do I have to delete the whole beta folder before installing a new patch? I've never done that with previous patch updates, though.

By the looks of it, loads of other people are also having this issue. So first I updated DayZ to 1.7.5.1 and then the arma beta patch to 101480. I'm using DayZ Commander. I can get to servers' lobbies just fine until I try to log in. First it says "something went wrong, disconnect and try again!" and soon after that it says "Loading character data. Please wait" but it gets stuck. I tried downgrading the arma patch but that didn't work. I also tried to launch both Arma2 and Arma2 OA from steam but no dice. Any advice?
