Spore.com will not register expansions

I've searched high and low out here, and all I could find were a few other people with this problem, but no solution.

I got core Spore a few weeks ago (from Steam; I did put the CD key into Origin and I've been able to log in fine), but only picked up Creepy & Cute and Galactic Adventures last week. In-game, they both work fine. But even after registering their CD keys into Origin, the Spore website wouldn't recognize that I own them, and I specifically can't share anything using DLC parts. It's uh, really annoying honestly.

What I've tried:
- Registering the expansions' CD keys to Origin

- Reinstalling the games from Origin
- Logging into every version the game (core Spore, Creepy & Cute parts pack, Galactic Adventures) from both Steam and Origin

- Clearing my Origin cache

Nothing has worked so far. I contacted EA help a few days ago, and they re-registered the expansions to my Origin account and had me clear the cache again. Didn't work either.

Pretty much at a loss about this? But I wanted to put somethin out about it.
