Is black the color that you use to clear the backbuffer? Try changing it to red and see if you end up with just a red screen.  It is possible you are not loading your textures/models correctly and it works on your box, but not on your friends.

Changing the

[code]

backbuffer.clear(color.black);

[/code]

to

[code]

backbuffer.clear(color.red);

[/code]

could help narrow down the cause.
