Lyne, I am very sure what I stated above is true, albeit vague. A simple reinstall on the same machine with the same hardware and software should not require a new code, however hardware changes will sometimes require a new code (even if you did not reinstall P5... just added RAM and a new video card for instance), and installing on a new computer will definitely require a new code. I've used other programs that use similar schemes, and I hate them. :( Movida, A lot of people agreed with you and those debates here were long and heated. CL had already made up their minds... and made an investment in the technology to implement this, so they weren't going back no matter what we said. Phoenix
