FSX - PMDG 747-400 Queen Of The Skys. I am having FMC trouble!?

Question

When ever I press EXECUTE on the FMC, it simply goes blank for a few seconds then reappears with no flight plan loaded. It is really annoying. If anyone has any advice or a link to a bug fix it would really help.

Answer 1

Are yo sure there is a route in there? There has to be atleast 1 waypoint in the RTE page before EXECuting will actually store a route. Make sure that there are actually waypoints in the route page.

(page 2 and onwards must have at least some data in it)

Answer 2

It all depends on what you pressed BEFORE pressing Execute.
