#21 "The code is generated using unique hardware identifiers. No personal information is used, and we don't check the contents of your drive except to locate your copy of Poser and Pro Pack" OK. That tells me WHY fdisk will not make any difference. And WHY the authorization will still work. So that means it's based on our hardware. So does this mean what I think it does and every time we upgrade our systems. For example: a new video card. That we will need to re-register. To get Poser to work? ScottA
