Arma 2 Beta patch opens Arma 2 not Operation Arrowhead

[Echelon niner 0]

Hi all,

i have been having trouble with the arma 2 beta patch recently.

basically whenever i want to launch the Arma 2 beta patch to open Operation arrowhead and play Dayz it seems to only open the original Arma 2.

i have tried many things to et it working like; restarting steam, reinstalling Arma 2 and Operation arrowhead, reinstalling dayz, deleting the beta patch and installing the latest one and running steam and the game in admin mode.

any help on this would be appreciated because the game cant be played properly without fixing this

thanks

I have had a similar problem lately, whenever I launch my operation arrowhead on my other CD key it opens up in arma 2 free. If you figure out a solution, I'd love to hear it because it sounds like we are having relatively the same problems.
