"The server is running incorrect version of the server side application."

[MrKevlin 0]

I've been playing the game for about a week now with no problems at all. Just before a server restart I took a hit from one of the zombies as the server went down. Now whenever I try to join any server I get the message :

"The server is running an incorrect version of the server side application. You cannot play on this server. If you are the server admin please contact the Day Z Staff" after I connect.

I've tried reinstalling my game as well as the mod itself but there's been no changes. I also tried respawning my character several times to see if that would solve the issue but still nothing

Does anyone know a fix or how to actually get playing the game again.

I've attached a screenshot of what I can see when I try and join.
