Hello, Just I am the only one who can't get unlocked. Never did a response code and all that before. I entered my serial number like shown, I went to the website. Entered my old Poser4 serial number and then was told the response was wrong. I tried to redo the process but now I can't get to the Curious Lab website because it stops after I hit register and says the response code is wrong. Any ideas what I did wrong. I am assuming that the 0 with a line thru it on my serial number is the number zero and not an O. Any ideas? I tried to call Curious Labs but got a recording. Bill
