I signed up for the free course Introduction to the New Microsoft® Office Fluent™ User Interface. When i click on any of the links, ie module introduction, or navigation overview, i get an error at the lower left corner of both ie7 and firefox that says "error on page". I also have tried selecting all the videos, to download them, but i again get "error on page". When i click on "begin this course", i get error on page. I am using windows vista, 2gb ram, latest updates on browsers.
