I have purchased the Reality XP FLN & FLT Software. I've found their user installion process beyond my capabilities. I've made too many mistakes that crashed FSX and worst Windows 7. I am trying to install the STEC 55X Autopilot, The ST645 & ST360 components. This part of the configuration file would be helpful. I have been able to insall the RealityXP GPS530WAAS GPS Sucessfully.Thanks for your help,Bob
