Steezeburger had the same problem, and last night or so I told him to open up the GC window and send one of his own graphics to game from there. And then it should work with any other graphic he tried to send to game from the site. He tried it and it worked for him, so thats one thing you can try if you're still experiencing this. Cause thats what I did a while back when I had this problem and it worked for me.
