Hi AllSince I installed Vista Ultimate several days ago, for some reason I have lost the ATC sound.I am contemplating rebuilding my CFG file by delating the present CFG and restarting FSX.Presently I have several third party add ons.MyTraffic X.ASV. 6.5FSUIPC registered versionSeveral Pay ware aircraft.If I do delete the present cfg file do I have to reinstall my third part software.Tks again for any advise.Kenny G.

Hi,Very rarely do add-ons write to the .cfg file. AS is safe and so is FSUIPC.Jimhttp://www.hifisim.com/Active Sky V6 Development Team Active Sky V6 Proud SupporterHiFi Beta TeamRadar Contact Supporter: http://www.jdtllc.com/AirSource Member: http://www.air-source.us/FSEconomy Member:http://www.fseconomy.com/
