In Game Origin problem

Solution:
1, Switch the game to windowed or windowed full screen mode in the options menu

2; Access dlc menu ingame (either at a workbench, or simply select the "invite friend" option"
3; Switch game back to full screen
4; enjoy

For me, it worked perfectly. Others report having to repeat the process every time you start the game up though.

EDIT: today, it stopped working again, and the solution above no longer does anything. I'm led to conclude that it's not on our end.
EDIT II (for whom it may concern): After extensive testing, I concluded that the problem is the following: For some reason, if DS3 is started up in fullscreen mode, it conflicts with the OIG overlay. However, as far as my testing goes, if DS3 is switched to windowed, vsynced mode and then back to fullscreen the first time you run the game on a given day, it WILL work for the rest of the day, even if it is booted in fullscreen mode. The easiest way to see whether it works, is booting up the game and checking whether the little OIG notifier pops up in the bottom right corner of the screen. If not, follow the steps above, and restart origin. With this method, I haven't had any trouble accessing the online functionality for the past few day.
