Tricky FLEXLM aw.dat setting for Maya 2008

I was setting up the aw.dat file by putting the Ethernet address in it,but the license application refused it. Turns out it's because I put in the address shown on "FlexLM license utilities", and it includes all three of my Ethernet addresses: one for my physical network card, while two for my VMWare virtual network card. Removing the virtual ones and put in only the the Ethernet address of my physical network card solved the problem.
