Thanks Rocket !!!!
You pointed me to it by the path - I have two installations by accident. When I originally installed AH I put it on my E drive to keep it away from my main programs etc but when I was happy with it and did a clean install of windows next, I had put it in c/programs. I had forgotten this and was busy fiddling with the now defunct e drive installation - DOH !!!
Now I have changed proper program all is well.
thanks again
