License Transfer problem

Hello,

I'm trying to transfer the license from na old computer running VisSim 8.0B to a new computer. I tranfer it to a USB memory stick using the steps on the webpage http://www.vissim.com/support/install_and_license_activation/license_transfer.html. The I try to transfer it to the new computer, but I get the message "License already transfered". My old computer stills with licensed VisSim and the new one still unlicensed. What am I doing wrong?

Thanks,

Alexandre Navarro
