From BGL to APT?

When I uninstalled an earlier version of Airport 2.0 I accidently deleted the .APT files I did foran Fs98 scenery project. I still have the .BGL scenery file and now I have Airport 2.6 installed. I'dlike to update the scenery for Fs2002, but I'm not sure which tools will do the job. I did sic "Scdis" onthe BGL in -Multi mode and came up with a set of 7 .sca files. When I imported the .sca files into Airport I was able to edit the FS98 Scenery up to a point. That point was the six or seven errors Igot when I tried to edit the objects...Error in GraphDraw Section:Initialize:6 OverflowZoom=1 xLoc/yLoc= 11664840:1997. I'm assuming that part of this might be the fact that the Macros from FS98 are not installed in the new version of Airport? Thanks, Guys! ChristopherT
