Tracker Sound

HI..I decided to install the free upgrade from Perfect Flight for the TRACKER 3.0 but have found the sound I now get is the default DC-3 instead of the powerful twin engine sound the Tracker puts out. The sound folder in the Tracker has its own set of sound files and sound CFG.which are different from the DC-3..I removed the sound folder from the DC-3 from my hard drive on to portable hard drive and I still get the DC-3 sound on the Tracker.. Cant seem to get a response from Perfect Flight but any ideas would be appreciated.Thanks..TH
