I just recently installed JSRS 1.5 for Operation Arrowhead. I pasted the @JSRS_1.5 and @JSRS_ACE folders into the Arma 2 Operation Arrowhead, and then I set the launch options in Steam as "-mod=@JSRS;@JSRS_ACE"(without the quotation marks). The mod works great and sounds great, but I used to be able to load up all Arma 2 maps(including all the DLCs) in the armory and editor . Now I can't and I'm stuck on what to do about it. Thanks.

Additional Details:
-I have no other mods installed
-Installed latest patch

double check if you installed both ArmA2 & ArmA2:OA in the same folder, and you should have a launch icon called : Combined Operations? Does it work without the mods? Reinstall your patch just to be sure all is installed right.

It's installed on Steam, and I launch it through Steam, so I don't know what icon(desktop icon?) to look for . Both are installed in the Steam\steam apps\common folder. It works fine without mods. It still works with the JSRS mod, but the maps that showed up before without JSRS no longer appear in the armory/editor. Patched my files and still only get Takistan.

did you install CBA?
what time was JSRS updated on Steam last?
