Instead of downloading nasa.all and editing it, you can download nasabare.txt instead. The latter is exactly the same as nasa.all with the edits being suggested. That way you just need to rename, and not edit.
Nova also downloads KEPS files from the internet without needing to create/edit a file.
In the Nova main window click on Kep. Elements Internet Update Configure Download
In the configure window that opens: Fill in 'Download To:' with where you want to store the download on your local machine. (I just put it on my Desktop)
Fill in Remote URL: www.amsat.org Remote files: Click on the 'Edit the file list' icon to the right of the data window.
When the file list opens uncheck all of the existing options since those files don't seem useful to retrieving amsat keps.
Then you might need to use either Add, or Replace to enter amsat/ftp/keps/current/nasabare.txt
Then save the changes with the Nova OK buttons in the layers of these menus you just negotiated through.
Try the Kep. Elements -> Internet Update -> Start Download
I've found that Nova running in true windows OS fashion may require to stop/restart the program so don't be surprised.
