The main reason I bought Spore was to spend time with my friends even though we have different schedules but when ever I try to share my creations it says "Sons of Marz" was not successfully shared. And I am getting all of my friends content while they are getting none of mine. Please someone find a way to fix this, I tried useing the information above, but the files were not found on my computer, if it helps I am an XP user . This problem is very irritating and makes me feel like I am using an old buggy game.
