Re: Lost Awakening Disc - Can I download a new copy using the old Key?

Yes, your "product code", (as EA calls it now) is valid for the EA/Origin store digital download version.

1. Install the EA/Origin client (if you haven't already)

2. Log-on with the same account you used to register the game in the first place

3. Select "Origin" from the top-line menu

4. Select "Redeem product code" then enter yours

5. Download and install

Voilá!  Dragon Age Origins: Awakening.  😕mileyvery-happy:

[EDIT: Same process is good for the base game and/or DA2 as well, so you'd never need a disc again!]
