I buy PC #1, and load Poser on it. After a while #1 crashes or is stolen or destroyed in a fire, or merely I decide to buy a better computer, namely PC #2. I try to install Poser on #2. It refuses, and says that I already have Poser on #1. How to I convince that CL that Poser is no longer on PC #1? Or must I buy a new copy of Poser every time?
