Probleme mit Froogle

[glat...@gmail.com]

I have a Problem using Froogle (for the first time, use it for months
without a problem) when i add a new product to the shopping list. I
have only a default shopping list with 191 articles in it.

Problem:
When ever I add product (Win XP, Firefox and IE) i receive a white page
showing in black letters: Not Found Error 404

The URL is: http://froogle.google.com/shoppinglist

Is there a glitch? Did I missed something, does it work for you?
