Guage problem

I have downloaded the Delta Airlines B737-800 Fleet (Kittyhawk) version. But the guages will not show up in 2d view.
It has a
[fltsim]
alias=b737_400\panel
in the panel section. But the guages will not show up.I have checked the b737_400 version and the guages show up in the plane. What is the problem ?
