    I have Corel Paintshop Pro X5 Ultimate installed on a desktop and am trying to load it on a laptop to use while traveling.  I am getting the error "serial number has already been submitted the maximum number of times for activation".  We had it previously installed on two other computers that are no longer in service.  How do we get this registered on a second machine when the system isn't smart enough to tell when installations are no longer in use?
