Scribo package

I'm trying to install Scribo. I would like to try it to use as CMS.

I've already installed Aida/web and it works.

But for Scribo, it seems http://mc.aidaweb.si/Scribo is not accessible. The url is not accessible with the browser.

With Monticello, I also get the same error ("Could not access  http://mc.aidaweb.si/Scribo"), see screenshot. 

I have followed the instruction on page http://www.aidaweb.si/aida/scribo%20start%20guide ("Download or install with Monticello the latest version from Aida/Web SqueakSource repository here.") ,

and used this command:

As I'm new to Smalltalk, it might well be that my Monticello command is wrong.

Thanks,

Best regards,

Nicolas
