I am having the same problem as well i've read the other forums and no fix what so ever even tried doing what Geez said. Nothing. I have played this game before no problem then out of no where I can not load into any game what so ever. I've uninstalled mods, bulldozed then removed bulldozer, removed dayz folder, verified game files, ran as administrator, updated drivers, updated windows, disabled cloud sync, uninstalled and reinstalled Dayz, etc. I was using DZSA Launcher i uninstalled the program thinking it could very well be my problem but nope same problem with DayZ launcher. If anyone finds the fix to this it would be greatly appreciated. I have spent countless hours trying to figure out this problem thinking I was the only person with it but it seems there are more than just me and I have not found a solid fix for the problem.
