Have you gotten a solution to this yet? I've contacted EA HELP and they've told me the online creator can't be added to the game...
It sounds absurd as the online sharing platform is part of the base game....
It worked! as soon as I bought Spore Creature Creator, I can register in game
It's on sale now
I've done all these steps (except for the cd key ones, I got support to give me a free copy). I have Spore, CAC, and GA all on both Origin and Steam but I still cant log in. I still get "An unknown error occurred during registration. Please try again" even though I have it on both platforms. I am playing on steam, but I tried playing on Origin too.
Even now in 2022 the first thing u did worked for me. Didnt need to do anything in the updated section aaaand thank u!!!!
