GreatSecurityAddon Rated 2 out of 5 stars

It shows the reputation data of each site/url we visit so that we can decide to go further or not;and also those in search results.I am using this 'helper addon'for the past several months.
But,now,suddenly it went out saying"failed to load reputation data,retrying shortly".Any clue as to why?I am using Firfox2.0.0.4.

This review is for a previous version of the add-on (20070501).
