Sonic_ban.xml gauge does not work....

Hi all,Firstly, I had downloaded and carefully installed per instructions,the Sonic_bang.xml guage, and associated wav file: whmm7.wav, andsound gauge: XMLSoundv2.gau.The code for the sonic_bang.xml gauge looks like this:(A:Circuit general panel on, bool) Sonic bang (A:Airspeed mach, machs) 1 >= (G:Var2) 0 == && if{ 0 (>K:MAGNETO4_RIGHT) 1 (>G:Var2) } (A:Airspeed mach, machs) 1 < if{ 0 (>G:Var2) } Then included the sonic_bang.xml gauge into my aircrafts panel, put the the xmlsoundv2.gau and whm7.wav file into correct folders in ..GAUGE dir etc..In short followed instructions per designer. OK ......when I load the plane into the simulator ( FS2002), I get a error message aayingthat the Simulator COULD NOT LOAD THE GAUGESXMLSoundv2.gau.Can anyone tell me if they ever got the gauge to work in FS2002?Thank you for any feedback.
