I have a problem with a stage I created

[Mudkip97]

So i made a stage but when I wanted to test it my game froze for some reason. I made the stage over Pictochat when creating it.

Here is a link to my stage: http://www.mediafire.com/download/ubdfb8x8g8gocpj/STGPICTCHAT.pac

A few information is needed befre anyone checks it out:
-DO NOT MOVE ANY MODELS FROM MY STAGE
-The stage goes over Pictochat
-If the problem is found please tell me
