Hey All.
I was pointed this way from the EA support team and asked to start a thread about it to get more information. I downloaded the deluxe game this morning but all DLC are missing from the game. Already tried uninstalling and reinstalling, then eventually started getting an error code for 327684:1 and saying download failed. I am just at my wits end, the game is there but the DLC seems to be inaccessable.

When you say Deluxe, do you mean the Ultimate Edition? And is this on PC?
This page has DLC installers for PC that seem to work better for most people. Some of the files are in the 'dazip' format. To install those you have to use DAUpdater.exe, which you can find in the folder where DA Origins is installed.

I went through the same thing not a week ago and started a thread, too. EA support helped me out though, and I posted the solution in the thread I started. Here:
I don't know if it will help you, but give it a shot. Can't hurt certainly.
