Getting guages to work

Hi,
As a relative newcomer to FS2002 I have been having fun downloading one or two extra aircraft. Most of these I have installed with no problems. However, having just flown Swansea-Dublin on the Air Wales ATR42 I thought I would download the very nice Czech Airlines ATR42-500 from simviation. The plane looks great and sounds great - but I can't get the guages to appear. I've copied them into the guages folder of FS2002, which has worked with other downloads - was this wrong?
Thanks,
Paul
