Hello Case120 and welcome to TRACTORFORUM!
I remember someone talking about something like this awhile ago. I looked for error codes and your model Case. What I found: (
Case Tractors - Lynx Applications ) seems to not be working or corrupted.
In the meantime, I'll be asking other members and staff if they have any resources that may help you, so please be patient

, and have a look around .
