Changing between DayZ and Vanilla ArmA

[Nergalwaja 20]

I realize that using the Six Launcher you can swap between various other mods along with DayZ, and I feel like playing some Singleplayer scenarios on Operation Arrowhead. I've launched OA through Steam, it takes me to DayZ with Singleplayer grayed out. I've tried launching ArmaII through Six Launcher with no mod selected, and I still get the same problem. I've tried disabling the DayZ mod through the expansions menu through the ArmaII main menu, but that doesn't work either.

Can someone tell me what I'm doing wrong?

Doesn't the launch option change through steam or something? I may be completely wrong.

I usually just drag the day Z folders out, launch as CO on steam, then drag em back in when iI'm done.

Use ArmA II Launcher, this will simplify everything for you. You will be able to switch mods on and off, run in Beta and run ArmA II without steam. http://www.armaholic.com/page.php?id=8241
