As I Private Messaged you, which you seemed to have ignored, the Add-On was failed. I assume it was failed because I hacked the setPrint command to also work as an event. It doesn't actually hurt the game, but I guess it scares him to have that.
Anyway, as I also said in the PM, to get it to work, you have to modify the files so the game won't know to block it. Of course that would be looked down upon, but I'm only trying to help.
