Ken: I appreciate your prompt reply. I believe that I followed your instructions. I have the Fly!2 Database Mini Tutorials, VOL!Edit V1.13, and DEXImport V1.2 and have been using them in the past. (I am an instrument rated private pilot and use the sim to practice instrument approaches. Since no one is providing updates to the last navigational data provided by ROTW, I have been adding the GPS waypoints and navaids as I need them without difficulty.) The only exception to your suggestions that I did was that I had to create a unique runway key (used in the runway pod) and a unique airport key. I made sure that they were unique by reviewing the unpodded files using VOL!Edit. I believe that they are linked together in the runway pod as it asks for both the runway key and the airport key. I could not find any documentation about how to construct the unique runway key and that may be my problem. The unique runway key I used was:3EB1D5EGAs I said, I am sure that it is different than any other runway key (unique), but I really don't understand what the individual characters in this key may represent and this may be my problem. Do you happen to know?I have been a quiet member of the forum for a number of years. It is a great sim, it is a shame that there is little to no support for it anymore.LarryG
