Creating flight plans without endless dragging of the red route

So,

 

Recently was working on a flight plan from Seattle to Narita. Was about to finish when I made some ... unexpected, unexplainable mouse drag/click combination which did something to the simulator, and it crashed.

 

Not really feeling like doing it again (but I will end up doing so anyways), is there a program that creates a .pln file where I could just enter the points (assuming it knows which points do and don't exist in the FS2004 database)?

yep. simbrief. create your flightplan and press generate OFP, or (operational flight package). once loaded scroll down to the flightplan downloads and find FS2004. export to the FS. I use the simbrief downloader for all my export needs (ifly, pmdg, wilco, etc.) load up the sim and load the flight. all info entered. tada enjoy your flight!
