Tells me I don't have Arma 2 installed

[itsjonny 2]

Okay so about a week ago, I took the main dayz mod and dayz lingor island map addon folders out of the arma 2 operation arrowhead folder.

the folders were "@DayZ" and "@Dayz_lingor_island"

I took them out because this tutorial to play takistan life told me to take them out and leave takistan life map addon folder in there, that folder only. So I did, it worked, played takistan life.

Now I'm trying to get back onto the main DayZ mod, so I put the folders back in there, and now when I try to download the latest beta patch with DayZ Commander, it tells me I don't have arma 2 installed.

Can anybody tell me why it tells me that, please? I really want to play Dayz now :(

When I run dayz, it tells me this..
