Latest questions about "facedub"

Where can I buy the boxed CD version Of Facedub or Facedub Pro? I had it for a long time on a computer that was running windows XP service pack 3.

I get access violation address 0065E429 in the module 'facedub.exe' Read of address FFFFFFFF. What seems to be the problem?

I keep getting an error message when I try to register the product. I've double checked and I am spelling correctly.
