You should post the script so we can give you an opinion.
Also, did you try to launch the cards in different order? Are you sure its not a particular card failing, the one you launch last?
Ill do that... As for launching them in different order, they all work fine. I can start 3, 2, then 1 will make it crash, or I can do 1, 2, and 3 will make it crash. Cards 1, 2, or 3 by themselves all start fine.
This was the guide:
