[Albert Lee]

when I follow the tutorial on:

http://wiki.squeak.org/squeak/6021

Installer squeaksource project: 'Installer'; install: 'Installer-Core'.
Installer universe
      answer:'username' with:'admin';
      answer:'password' with:'seaside';
      install: 'Magma seasideHelper';
      install.

I use an Seaside Image from www.seaside.st $B!$(B and when execute the
above commands, It fails on : installing
MonticelloConfigurations-UniversesFix version un.33.fix.3

I can't download the file:
