Arma 2 update help

[Colinz 6]

So today i updated the dayz update and that worked fine. But apparently arma 2 updated as well but i didnt download the update for some reason. So now i cant join most servers. I had a friend send the zip file for the newest update which i proceded to download. When the file appeared in my downloads I activated it to download the update. it mentioned that the files for the update needed to be extracted to work so i did that and finally got to the extracted files and downloaded the update, it said after this that the update had been applied, however, when i go to open the game to check the version, its the same old version and im having the same old problems. Can someone help me with this?

go into the arma 2 oa folder and go to expansions then beta and take the arma2oa.exe and put it in the arma 2 oa folder and replace the older one (just drag it in) it should work fine after that
