Hmmmm
Not sure how to fix this but try this :
1) Go to your WTF Folder and delete any Ratingsbuster.lua you find in the SavedVariables folder
2) It possible there is a bug in Outfitter causing RatingsBuster to bug. Update Outfitter at
http://www.wowinterface.com/download...Outfitter.html
You could try disabling all addons except for RatingBuster then test it. Then turn Outfitter on and see if you can get the bug to come up
3) If nothing else works try submitting a ticket on the ticket page for it
