Hi. We have recently been experiencing difficulty using truck doctor. The software has been tested using the canbox on a r1.4 reach truck.

However when we use the truck doctor cable, direct through the serial port connection it doesn't see anything connected. We have tried, several different trucks, we have tried 2 different laptop, and we have also had a new set of cables.
It all worked fine until one day, its just stopped working and we cannot seem to workout why. Has anyone experienced anything similar?
The laptop runs windows 10 and the tablet runs windows 7 both have serial connections. We have also tried re installation of the software version 2.01.005.

We don't know what else to try.
