So, after a loooong time of experiments, I successfully installed some mods (Dark Injection and Force Save). but for some reason it just does not want to work.
I have the Spore ModAPI Launcher pinned on my taskbar, and everytime I run it, this error message appears:

(If the Image didn't appear, the message is "Could not find default preferences. The data directory is missing or corrupt.".)
I tried going to the launcher's location in my files and run it from there, but it didn't work aswell. The game also doesn't even open if I run it from Origin!
Anyways, my laptop has 8GB RAM, 1TB of space in total(584GB free), and I had the Steam version of Spore, before getting the Origin Key and transfering it to Origin.
Please, help me, I was really excited to play Modded Spore, and I don't want to give up on trying to play it.
Edit: I forgot to mention, I have C&C, GA, and the newest version of Spore.
