MSDN licence for Dynamics AX 2012 R3

I have downloaded Dynamics AX 2012 R3 from the MSDN portal and I have also downloaded two licence files that say:

1. en_dynamics_ax_2012_feature_pack_license_file
2. en_microsoft_dynamics_ax_2012_license_file_x86_x64_11881264

I have never installed or used Dynamics AX before, so I want to know if the licence files on MSDN give me full functionality or are they just demo licences with restricted functions?

I opened up the licence files and they just contain text relating to Contoso which looks like a demo company. I don't want to buy a server and try to install this colossal software if the licence isn't going to give me full functionality.

Anyone know the score?
