It should work if you get Spore through Origin. Get Origin, https://www.origin.com/usa/en-us/store/download and right click on your Spore (on steam), Hover over Manage and click CD keys. Copy and paste that in your Origin library after going to Add a Game (by code) and, if no errors happen, you now should be able to log into Spore, whether launching it with or without Steam. You have to do this with Core Spore and the DLC.
