This started a while ago on my desktop and is still there despite several uninstalls, registry cleans and deleting every reference I can find to the program.
It however has been running on my laptop Ok till this morning when it got to 7% copying an audio Cd and froze. I backed out of it and on restarting gives the above error also. Is driving me mad and cant find any reference to this error anywhere.
Any assistance is appreciated
