Okay now I'm getting panicky again. I have WinXP and plan to reinstall it on my new computer. What kind of hellish tortures do I have in store for me? I don't understand why it would be so frustrating (I know I'm missing something) Isn't is just a matter of calling in your serial number and getting it reauthorized? And I'm assuming the same hellish torture would apply to Poser 5 if I wanted to upgrade again in the future? Again, I'm showing my ignorance, but what could be SO BAD that it would make someone stop using the product?
