Can't redeem Muck & Makers DLC. It's not on steam. Update: Got it but still can't get community pack

Hello,

I've been trying to redeem the Muck & Makers DLC so that I can run Spiral-6 galaxies? Apparently, it was mad in a way to incentivize players to make Get2gether account. Well, I'm here. Please gimmie my DLC. Looked through threads, only other post 3 years old. I am looking for help acquiring this part of the game and fear it's lost media somehow. Please help me.

Cheers
