Addon Requires Additional Items Rated 2 out of 5 stars

w/FF 3.6.18, & Fbug 1.7.3, this addon is self-disabled with an error:REQUIRES ADDITIONAL ITEMS...no hint as to what other items are needed...:-(

p.s. I would have give this 'no rating', since I don't feel I should have to give a rating for something
that I can't get to work in the first place that may be no fault of the addon...

This review is for a previous version of the add-on (1.3.1).
