Has anybody had any trouble with your software not connecting to the coach engine computer because of a "PC Failure?" I have identified the correct Port, and checked automatic restart, but still get the same error. Talked to Martin from Silveleaf at the Concord FMCA and he said to (1) Open Device Manager, plug in USB Adapter and port number should appear on the list. Next, he said to start VMSpc and set it to the correct port. Finally, plkug in the JIB and it should work. Well, it did but only one time. Since then, my system has been down. Thanks, Ron
