Got it. I think Im going to use the "request new winner" option, if you agree.

Hello sysedit.

If you already had this DLC and did not activate the code on your account, you should mark this giveaway as 'Not Received'.

From our FAQ:

When should I mark a gift I won as "Received" or "Not Received"?

• You should only mark a gift as "Received" when you have both (i) received the exact game described in the giveaway, and (ii) activated that game on the Steam account you used during registration. In all other instances, you should mark the gift as "Not Received" one week after the giveaway has ended.
