VPN maya license number

I'm almost done installing maya but before where I entered the network vpn license number where it was something like 111-1111 but now it's rejecting that number and asking for a new license number. I remember at the end of the install the instructions said I was going to have to copy and paste the current license number for maya with a new one but I don't know where to go from here. Please help as I've been stuck at this for several days now. Thanks
