Hi,<br><br>PingPlotter v2.03 was installed and registered OK on my NT laptop, but then my machine was swapped and the registration disappeared. Attempting to re-enter the code when logged in a myself gives error "Can't create key User". When logged in as administrator, the registration is accepted, and the nag screen goes away. BUT when I switch back to my own user id, I still get the nag screen. I appreciate that this is more of an NT problem than a ping plotter problem, but any ideas?<br><br>Chris<br><br>
