RFN Gauge in FSX steam edition

I have loaded the latest version of the RFN gauge into aircraft panel cnfg of aircraft in FSX steam. Although it appears in the instrument panel ,when selected it flashes momentarily [black square] and that's the end of it??
I have loaded it numerous times on an older computer with windows 7, but cant get itto work with windows 10?? 
Any help would be much appreciated  Thanks  Will.
