Guage problem

[ETaylor]

I just got this plane working for FSX- http://www.fs-tutorials.com/en/down_plane_C150_01.php

It works, and flies, but the guages are not working properly. They are black, with shapes inside of them, and the entire guage is not displayed. Other guages do not appear at all. Does anyone else have this problem, or know of a fix? Thanks.
