License transfer problem


I'm trying to transfer the license of a VisSim 8.0B from an old computer to a new one with the same version, but I'm having problems. When I transfer the license from the old computer to a USB Memory Stick, using the steps presented in the webpage, I get the sucessful message. The file "vissim.lf" goes to the memory stick. But when I try to transfer this license to the new computer, using VisSim License Manager and following the steps mentioned on the webpage above, I get the message: "License already transferred". My VisSim on the old computer stills licensed and the one at the new computer stills unlicensed. What am I doing wrong?

Thanks, Alexandre Navarro
