Many, many thanks to those that bunged in to this thread, especially Rog. It is a frustrating time when a pooter goes awry but it is fantastic that there are peeps that will contribute and get things going again. Off licence still open, was it?
Don't know what actually happened but a dodgy driver installation is most likely the cause. Ended up with a Windows Xp repair, went smoothly and everything is up and running again.
Much appreciated gents.
