mClock won't load on my N800. (os 2008)

Looking forward to using this useful application. Unfortunately when I press the mclock icon in Extras it tries to load and nothing happens. There is no message in the application manager log. I've tried installing versions 0.5.0, 0.4.0 and 0.2.0. Also I've tried installing from file.

Has any one had this problem?

Sorted - just needed to install more python bits
