Could someone please help here. I've somehow lost all data for making flightplans outside the US. When I enter a foriegn airport, it will not register and sends me back the the default US airport that I had chosen last flightplan. Any help would be greatly appreciated.

If you have been using AFCAD to install updated airport information, it may have corrupted one or more of the AFDFILES. Rename you updated AFCAD files (myupdated.bgl.UPDATED) and rename the default.ORIGINAL to default.bgl one at a time to see if you can isolate the problem.Another area could be some third party addon scenery you installed. Try deselecting the addon scenery in the Scenery Library to see if it fixes the problem.
