Program worked great until I installed an update to PC Tools Spyware Dr. Now I get a Failure between Pc & Jib message. I turned off the spyware. Same results. On all the other ports, the message is Port Failure. Green light is steady & red is blinking rapidly. I rebooted with no success. In the Diagnostic section, I found two messages with the dates that I have been driving. Message stated bad program. I removed the program and reloaded the program & the upgrade. Same proble,Failure between PC & JIB. Also lost my Trip data when I reloaded program (Tears) I love the program am on my second year with it. Help!! RV w/ C7 350 HP engine. AWPerry E-mail: By AWPerry
