I probably have no business replying to anything, as I am very new to PLC's, however.........You can go into your "rocksoft" file, I believe that is the file name, and tell it to pull the activation code from the A: drive, as opposed to moving the activation to the hard drive. If the computer dies, you still have the activation code on the disk. The downside here is the more you access a disk, the shorter the life span. There is a way around that, which is best left unsaid as it could be used for nefarious purposes. Look in the "help" file for instructions on which file to edit, and where it is likely located. I use an older version, on win98. It was located in the 'windows' folder if I remember correctly. You can get a reactivation code online, but your are restricted to doing so once a year.
