Projector not working

I´ve just finished a projector on a CD, that took about a week to finish, and takes about 2.5Mb in size.

Tested on my machine, on other machines and works fine.
The problem is that on my client´s michine it didn´t run, and stopped the machine. Had to reboot it!!!
imagine my situation…

don´t know if it´s because the file size (has some 3d animation on it at the begining, no sounds, ).
the clientes machine is top of line.

it shows nothing but a blank white screen and the machine doesn´t respond.

Need some help and advices on it…
Maybe making the swf to be loaded would help???
