Sybex CCNP virtual lab

I made an honest mistake. I installed the Sybex CCNP lab on a PC and
was using it for a number of months/weeks. During this time I must
have given the jewel case with the CD key away to one of my many
customers that needed a CD burned. I uninstalled the product from the
PC to put it on my laptop and then realized that the CD key was gone.
Sybex tells me I am out of luck since I had already uninstalled the
product from the previous PC. Does anyone out there have any ideas, or
mabe a copy that they don't use anymore? I'd be willing to pay for a
working CD key number. BTW, this is for Second Addition.

Thanks,
Lee
