Hi Guys,
No not resolved.
Ive reinstated, done all as suggested above and still no response.
Listed in device manager, ticked and where it should be on sonar device panel.
Next stop will be midi leads I guess, but still baffled as to what changes from when it first worked ( as good it was!) to 3 hrs later on the same programme.
Thanks for the help thus far, I am sure it must be something simple that I am missing, but what I know not!
