[amsat-bb] SatPC Win List Error

All,

I'm trying to get some predictions for Field day on winlist and when I open the program get the following error: ungültige numerische eingabe.

I think it has something to do with finding the kep files, since if I click anything else it takes me to a file open dialog. I select a file and then try to change the default location and I get this error: e/a-Febleu 32

has anyone seen these issues and know how to beat them?

Thanks in advance. Rick K7TEJ
