I carefully eliminate the license from all disks. I carefully remove the program file using the uninstall that comes with the program folder after having restarted the computer. I delete the folder with the remaining two licenses in the folder. I download jv16PT and install (a trial for now). I then download the hour old License.xbin to the desktop and use the autofind feature. The program can find it. I use the manual option; restart and the warning apears that it can't operate without a license. This happens with the other computer pretty much the same way.
