Martin, We going a little longer than 30 seconds, actually 90 8-) And in my pre-coffee blur this morning I misspoke. Once you have registered and unlocked on a specifc machine, you never again need to re-register and re-unlock on that machine, even if you re-install again and again. Actually, even if you reformat the drive, the code generated the first time you registered is preserved on your hard drive. Maybe if we didn't supply you with software, you'd be more of an ally ;-)
