Well. I found a way to make the trainer work with the steam version.
Replace the exe from the file (see Link), with the one on the Steam\steamapps\common\spore\SporeBin Folder. Run the game from steam. The latest trainer works like a charm (1.5001), except for the food, everything else works. I still need to find the newest nocd crack for the galaxy adventures expansion (Found 220.127.116.1188 and the one on the steam folder is 18.104.22.16818) :-/ Anyways, I hope you guys find this useful. Happy New Year. :-D
