A few problems have been holding me back from finally being able to play this game. I bought Arma 2 and OA and downloaded the DayZ commander. Everytime though whenever I go to install Arma 2 through the downloader it says "cannot access the file." I thought maybe that I should reinstall Arma 2 and even after doing so it still doesn't work. The file is there and everything I just don't know what the problem is. If anyone can give me some good insite I would very much appreciate it.

Still didn't do anything. I copied and pasted the address and everything and it still did not work.
