I usually update my Keplerian elements to track the birds with T.S. Kelso's SpaceTrack TLE Retriever 3, stand alone Windows program. It has worked flawlessly for many years on my laptops running XP and Windows 7. Starting this week, I get an error on all three computers. The program downloads the master lists fine but when I click the button to parse them out and check for errors, I immediately get "Unhandled exception has occurred in your application Spacetrak .... Index and length must refer to a location within the string parameter name length. I am using version 3.0.1.3 (2013Jul17) and even upgraded on one computer to version 3.0.1.5 (2014 Dec18). I sent an email to T.S. Kelso and attached a debug file but have not heard anything in several days. Any one have the same problem or know of a fix? Thank you. Rick WB3CSY
