FSX won't load saved flight plans

Hi guys.I removed some addons that i didn't want recently and found out that my fsx was not working properly so i did a complete uninstall/reinstall. Everything worked fine except now fsx won't load any of my saved flightplans properly. If i plan a flight from the flight planner menu on the main menu and save it, the plans will load after loading the sim but when I checked my gps, all the waypoints are there but the distances were something ridiculous like 6997 nm between each waypoints and no flightpath. The only way i can load/plan a flightplan properly is when the sim is already loaded using the flightplanner menu from there. So that means i have to redo every flightplan for every flight that i do! That's really time consuming and well...really sucks big time. I hope you guys can help.cheersgaza
