Forum:How Do I Add Packs?

I recently bought the game off Steam. I have four different pack codes, obtained from different individuals, but when I enter them into Register Game on Steam, it says Invalid Code. I'm told this is a common issue.

How do I redeem my packs?

Are you sure they havent been used already? Most of those codes are one time use. ReapTheChaos 13:36, July 10, 2011 (UTC)
