Cant Launch CO/ Cant get into game

[WILL_ 0]

Hey guys,

Everything was working great, went away for a few days and returned to the new patch. Now when I try to launch CO (through Steam) I just get a cmd box flash up for a few seconds and then dissapear.

I try running Arma 2 and then OA to establish the registries but to no avail, it still wont launch.

I follow the instructions in this thread: http://dayzmod.com/forum/showthread.php?tid=991

And put my Arma2 AddOns folder in the OA directory, but when I launch OA It does not come up under expansions and therefore when I try and join a game it says im missing the cheneraus file.

Im really at wits end here, please help.

Will
