True brother, I was able to somehow get it mostly working, likely through sheer chance, but I couldn't download C&C for some reason, so I deleted all the Spore stuff and that fixed it, but sadly GA broke again ☹️. I will be here to back you up.
I have deleted all Spore AND EA (All I have is Spore) stuff except for a good chunk of the roaming files, and did so very thoroughly using a PC cleaner, I have restarted my computer countless times, obliterated the cache, and downloaded and opened Spore and C&C one at a time, all to no avail. Update after update of who knows what has fixed nothing but the passage of time. I feel as though this is an EA issue and not a user issue, as you can't even launch GA through EA but have to do so by finding the application in your files and launching it from there, otherwise it will just launch regular old spore. To anyone else with this issue, I recommend trying to open GA a few times before giving up on seeing if a fix works, because it's just that unstable. GA worked with no issue on Origin.
