Thanks Gerry,
I did all those things including a registry clean out but it simply will not happen on this machine.

I know that they will work together, a few threads on sites that contain sensible discussion on NX usage and not just troll type posts have indicated just as you rightly have that they will work together.
It appears that there is some conflict on my machine that is causing the hassles.
I basically wasted all of yesterday mucking around with it and now it sounds like a job for next year.
