This isn't an OS problem. It's a CS problem. I use FS Navigator to plan all flights. Once I import a plan into the FMC, I get all Lat/Lon coordinates only....for FS9 of course. I then have to manually delete all of those coordinates and manually input waypoints, NDBs, VORs,etc. The FMC doesn't recognize fixes at all like Fix01, Fix02,etc. The big problem is that FS Nav has the most recent Airac cycle but the FMC doesn't. So, from a departure airport, depending on the runway of course, you have to see what waypoints, VORs,etc, are available for the departure runway based on the aircraft's display...using the 10nm range helps with this, and then enter them into the FMC. Many times the most suitable runway won't have any available, so you have to improvise the best you can based on the nearest available waypoints,etc. The flight track may end up looking like a steep 90 degree turn after lift off but at least you'll have a normal flight track afterwards...hopefully! :P
