Could You run DAOriginsConfig.exe from bin_ship directory and tell me if You have a CD-Key in register? I have the same issue for at least a week.
Nope, no key listed in the DAOriginsConfig.exe program.
Ok, try install patch 1.05 manually from bioware site, if after that it says error while launching the game You have same issue as me. Repair the game using Origin then Download DAZIPS with DLCs and install them manually. For few people it worked perfectly, but I can play only standalone campaign (every attachment to main campaign doesn't trigger). Hope this help for now, until EA will finally do something with all of the bugs.
I found how to "trigger" them:

it works with every single not standalone campaign. Hope it will work for You as well.
