Fsbuild-2 Flight Planner

I recently purchased FSBuild. I use FSX,iFly and Radar Contact.
I loaded all these applications onto my D; drive. I followed the instructions in the options menu. (It does not have Radar Contact as an option for some reason) to direct the path to D;\Microsoft Games\Microsoft Flight Simulator X.

I great a flight plan but it does not show up. I finally found it under c:\(user name)\My Documents Flight Simulator x Files????

I copied it over to the proper iFly\737NG\navdata\FLTPLAN..Did I install something incorrectly??
any advice would be appriciated
