working fine all night, logged off, turned off pc, turned it on now. launched the game same as i did yesterday. already excluded the entire folder from the defender. no idea what is going on. hm please help.
This is a common error with v83 servers, I assume it has something to do Win8/10 or the GFX driver, most of the time relaunching the client until it does load does the trick. If this error appears BEFORE the game attempts to launch, you MUST restart your computer. Edit: Oh, I see @Cynn answered this in the chatbox already, my bad!
It worked restarting the pc. Thank you for the info . Perhaps a sticky on the question and answer for this can help others later down the road.
