Freemium 757-200 by Just Flight FMC Problem

  • So, when I go to RTE and try to find a flight plan that I've already loaded into FSX:SE, there is nothing there and appears to say "iiiiiiiiiiiiiiiiiiii" and when I reload my same flight plan, restart the FMC (turned it off then on), go to RTE and click "iiiiiiiiiiiiiiiiiiiiiiii", it crashes my game. I would really want to practice on this seemingly nice aircraft before upgrading to more advanced systems. Please tell me the necessary actions I need to take to fly this work of art.
