Help! I'm getting error "2, 8, 4, 11, 101, or 13" when trying to install.

What does this mean?

These errors indicates that the Online activation application cannot get passed your NAT router or Firewall. If you cannot disable your firewall I suggest that you try the "Activate through another Computer" option.

Once the steps have been followed, you will be able to activate the program without using the online activation feature.
