Arma 2 OA Does not Work- Joining from a Dayz Client doesn't work Either

[hoppieeatpie 2]

So I've been playing Dayz for about a month now with no problems, and had it downloaded from steam, but one day when I clicked on a server to join in either Dayz Clients (i have both) it gives the checkboxes thing and loads up, then goes back to the screen previous from clicking the server and I have the Arma 2 cursor but I can't click anything. I've sat there for awhile and it hasn't done anything. Also loading Arma 2 OA from steam does the same thing. Help ? ;)

Have you verified the game files through steam?

use DayZ Commander, reinstall or update everything, go to setting an mark "Replace original Arma2OA files with Beta so Steam works" and try again ^^

Have you verified the game files through steam?

Ya I did, and It came up saying "1 files failed to validate and will be reacquired"

I then clicked close but nothing happened....

I also tried it again and the same thing came up..
