dragon age origins and awakening download

It takes you to the 'game information' screen. I saw where someone said they'd found it by ' go(ing) through Origins, click(ing) on the Dragonage game (the name, not the picture). (Also, I'm not incredibly tech savvy, so if anyone could give me the five-year-old computer user's version, that would be great.)

I've attempted removing the DA: O-A folders from my Program Files and from the Dragon Age folder, but that didn't work Awakening still isn't available for 're-downloading.' Is there a simple solution (do I have to empty out my Recycle Bin?) or did I just waste $15? Do I have to purchase Awakening again to download it? I have searched all over the Internet for a solution and have yet to discover one I don't know if anyone else has even had this problem, but I would certainly appreciate a *speedy* reply.

However, Awakening still appears in my order history, right alongside DAII. I assumed this was natural and that I would simply have to log in to Origin and download Awakening again, but I can't find Awakening under the My Games tab. Unfortunately, I had to uninstall and reinstall Dragon Age: Origins, and Awakening disappeared from Other Campaigns. I purchased Dragon Age: Origins - Awakening (PC) and Dragon Age II (Mac) and downloaded through Origin.
