can't start a new document

I may have no prior experience of autocad, but I'm pretty sure what it is doing isn't quite right. When clicking on the IPub icon, then 'New', an options window titled 'Insert...' opens. If I click on the 'New' button the same thing happens. If I click on 'Insert Model', I get the same dialogue window. I have started following a tutorial and I cannot get the 'New' > file types window that the video author gets.

I did a reinstall (not an uninstall > reinstall) and the problem persisists. It is the 2013 version on an education license. 

Can anyone help? If no, then I'll uninstall and try a different version.

Thanks
