Thank you all for your reply. I called Nemeschek, told them my situation. They said to provide me a serial number for the PC I would have to "purchase" one from them. It would cost $300+. I just upgraded from MiniCAD 7 to Vectorworks 9 last year and paid $600 for it. I work alone, so every penny counts - $300 is alot of pennies.
Help!!! - I gave up on my Mac G4 and switched to a PC running XP. However, I would still like to use my VECTORWORKS ARCHITECT 9 on the PC. Would anyone be interested in swapping serial numbers for a PC version of Architect 9 for my Mac version? If so, email me! Thanks. J
