I’d guess outdated keps (maybe a satellite that has reentered). Try deleting the keps files and restarting.

Hi,

I had not started the program in over a year, and yesterday when I decided to get it functioning again, I get a constant error screen that says:

"Ungultige Gleitkommaoperation" the screen just keeps repeating..and the tabs are greyed out

I'd rather not delete and reinstall if possible

Any help appreciated

73, Ted
