Has it ever worked properly? A device I have with a similar digital rotary control had a bad connection on one of the four output wires, same effect, whatever way I turned the control it made no difference. It was like I was turning the control the same way.
yeah use to work flawlessly
Have you tried a factory reset? You can also do a factory reinstall of the software. The links are on the first page.
thanks Paul tried factory reset no joy same issue
