Installation of Dynamics AX 2012 R3 (Import demodata)

Hi,

I am installing the Dynamics AX 2012 R3. My AX installation is over, I am in the step to import the demo data. I am following this link:

http://tech.alirazazaidi.com/how-to-import-contoso-demo-data-to-dynamics-ax-2012-r3/

for completing the the installation. But on that I need to import the "MetaDataXMLGenerator.xpo" file to the dynamics AX. I struck on there. If I open my Dynamics AX. I couldn't see the company details or any thing else on the screen. It shows something called initialization check list. Can you guide me what to do next?
