VM /ETC

Ok, I click the http://www.vmware.com/products/esxi/.link and it sends me to the VMware ESXi 4 & VMware Go download page, which shows it to be a free product. But when I clicked through got the license, downloaded the .iso, installed & registered, it says it's a 60-day trial… Am I doing something wrong here? The software must communicate with the mother ship somehow, because I've reinstalled and wiped & reinstalled, and get the same results. I don't want to get to the end of the 60-day trial and have a non-working installation.
I realize this is a slightly old post to be throwing a question in on; got here through a Google search and a link from another post (vmetc.com/2008/08/10/whats-the-difference-between-free-esxi-and-licensed-esxi/). I'll check around elsewhere to see if there's more info.
Thanks!
