Arma II Beta Patch Launching Original Arma II

[Waymer 0]

I recently got Lingor Island for Day Z, and I played it for hours with no problems. But me and my friends felt like playing in Cheranus, so I went into the expansions and disabled everything associated with Lingor Island. We were able to play Day Z fine after that, but when I next launched the beta patch, it launched the original Arma II. All of the menu buttons were out of place and when I managed to reenable the lingor island mods it would launch and dispaly the lingor island loading screen but soon switch to the original Arma II loading screen and I would be in Arma II instead of Op Arrowhead.

I even tried uninstalling and reinstalling both games entirely. Does anyone know a way that I can fix this?
