Retrieving FPL causes crash

[carmichaelalonso]

Causes "Windows is checking for a solution"...

Repro:

•      Open IF, set an FPL
  

•      Retrieve it from IF
  

•      Hit Enable Autonav
  

•      You get a popup “Windows is checking a solution for this”
  

•      App crashes finally
  

@AR-AR-AR - could you look into this?
