I posted a couple weeks about an issue I had with my Pro700 monitor. When I turned on the combine it gave me this wonderful little message.

According to the Case mechanic this apparently is caused by some software glitch. He did a fresh install on it and the problem disappeared, for about a day... I turned on the combine the other day to try out some corn and the message appeared again, so instead of having the Case guy come out again I decided to see if it worked in the Magnum. To my surprise it did, so I switched it over to the tractor software and everything still worked so I went back to the combine with it still in "tractor" mode and booted the monitor. It booted fine, just gave me the expected errors. I then switched it back to "combine" mode and everything works again.

I'm wondering if there was something wrong with the data on the USB key, or the monitor itself. To be safe I deleted everything off the monitor and the USB key and will start from scratch the next time I head out combining.
