Not so far Geez. I wiped the dayz folder and did a complete install from scratch. So far, so good.

I am having the issue with the overlay not on. I have no keyboard or mouse input. This is both offline stress test and online. Dayz only. I just alt tab out and kill the game with task manager. Game starts correctly offline but once I am in-game, I lose complete keyboard and mouse interface. I I start the game online, the portal screen works normally. I choose options and servers etc perfectly. Once I am ingame, same problem. Up until yesterday, it was working great.
