I have been using Winorbit for years.
I normally download 2 line Keps from the internet and save it as a .txt file in a file name "Keps" . I boot Winorbit, select Satellite..., Edit, Database, Update from file.
List files of type = All Files(*.*) Find the file and click it to put it in "File Name Box" Click OK, click all OKs Then immediatly select File from the menu bar and do a "Save Database"
