EA won't add Spore to my Origin Account

I had the exact same experience as you for multiple YEARS. In my case I was only eventually able to get any progress because I was lucky enough to get an agent who was actually willing to help. Every other agent literally says to contact the retailer. Well, guess what? In my case EA was the retailer! I bought the physical discs directly from EA! The agents don't know how to deal with that though. I learned that the problem is deeper than poor training though. The serial numbers for the game don't even appear to be associated with anything. Not spore, not the creature creator, and not galactic adventures. Like you I also had proof that I owned these titles because I registered with Spore.com and I even had achievements on my account proving that I not only registered the game, but had created content and played online with it. 

Now, once the account is "fixed"you have to download Origins and then download the game again from there, but I strongly advise against doing this! I deeply regret getting online because they did something to the Origins version that makes it less stable. Worse though is that when I tried going back to the disc game the new bugs persisted. Spore has always had stability issues, but these are the new bugs I experienced as a result of getting the Origins version:

- In the creature stage dying while migrating to a new base causes a crash half of the time now.
- Every single time I exit without saving the game in the Tribal stage the game crashes. It also frequently crashes in the middle of combat.
- Oftentimes the game will crash while opening the settings menu, which I have to do every game because it doesn't remember full screen settings ever.
- Sometimes the game will crash while saving!I have NEVER had this happen before in the last 15 years! Not even once! And now in a single game it happened twice in the Tribal Stage, 5 times in the Civilization Stage, and dozens of times in the space stage! In fact, saving the largest source of crashing in the space stage now! This is especially bad because the game still doesn't have an auto save! Thankfully it has a save backup slot, but that just means rolling back to the save before last which is horrible!

That last bug is the absolute worse! I haven't been able to make any game progress in the last 3 HOURS because every single time I save the game after making some progress the game crashes on saving!!!

Overall, this is NOT a good game anymore! And this is a worse situation than EA simply choosing not to fix bugs. EA actually introduced it on purpose! The problem is though that I can't figure out exactly what they did and where. Closing origins and blocking the process didn't fix it, and it can't be an issue with SecuROM because Spore already had that, but then what else could it be?

People in this forum say you have to repeatedly delete GraphicsCache.package(s) from AppData>Roaming>Spore but that doesn't help and it's not something I had to deal with before. Not in 15 years at least. People also say to run in compatibility mode and as an admin, but that doesn't help either. 

In any case, here's what I wish I did:

1.) Continue playing offline.
2.) Install the Origins version within a virtual machine or on a complete different computer.
3.) Copy the "My Spore Creations" folder from the computer you play on 
2.) Upload your creations from the second installation only. 

I hope there is a way to go back to stability, but until I know exactly what EA did to the game install, or what DRM is breaking the game, I can't. If it is DRM though the irony here is that the pirates probably get to play the game for free WITHOUT bugs meaning that paying customers like us who supported the game from the beginning are treated like garbage for doing.
