Steam users unable to create Spore account or redeem game on Origin

Hello all.

I brought Spore and Creepy and Cute, as well as Galactic Adventures on Steam previously, but I created a new Spore account using a new EA account with a new email.

When I created the account, it shows me this page:

I can understand that that account does not own a game of Spore, but there isn't a link to the Steam version, so am I supposed to re-purchase the game on Origin? I have a physical copy of the game as well, so if I were to buy the Origin version, am I supposed to transfer the product key from the physical version to the Origin version?

I just want to make a new Spore account and start fresh and new again.

Thanks.
