It seems strange that only the TF entries are gone...or are you telling us that the file is now the default file...as in the program rebuilt the file...as it will if it is missing. While this rarely happens, it can ....which is a good reason to make a copy of the completed file....just in case. The easiest way to fix it is to download Holger's file and import it and then re-number. If the file was indeed rebuilt, then you will be installing scenery as well.
And you will have to move and then fix the
ai enteries.
