Problems with 1.01 UML pages (#3)

The 1.0.1 UML models in Github at

http://htmlpreview.github.com/?https://raw.github.com/openEHR/reference-models/master/models/openEHR/Release-1.0.1/UML/HTML/index.html

are not working correctly. Clicking on a diagram no longer opens the underlying model as it used to, and the Classes / Dictionary links appear to be missing - I get a 404 error.
