Since the last update i can't get into unofficial servers anymore. I've got a new pc since a few months and it should not be a hardware problem. I've been getting the same messages:
0x000400f0 - Client not responding
You were kicked off the game (BattleEye: Game Restart Required)
and everytime i check options it says that i have unsaved changes and asks if i want to discard them yes or no while i haven't changed a thing. I tried removing dayz/battleye and the revalidating process but it never worked. The last thing to try out is uninstalling and reinstalling my gpu drivers.
And the regular launcher can't find the mods for the server while i have them in the modsfolder.
