Dragon Age: Origins
I believe this is because of the change to there site. Which is connected to your Game.
find your dragon age folder, you may have saved it else where but this is how I find mine.
D:\Steam\steamapps\common\dragon age ultimate edition
Once your in there find the file that says REDIST should be near the bottom. In there run the file that says DAOU_UpdateAddinsXML_Steam, when that finishes run the other file called DAUServiceSetup_Steam. Start up your dragon age ultimate and hopefully everything should be working.
This worked for me.
