Yep, mine also show as all 0.0
I guarantee you eBay has changed the API so that the data can no longer be obtained externally.
DSR Watch probably became too popular and/or too controversial for eBay, so they simply removed the ability for this site to fetch the data. I'll bet this has a lot to do with the Seller Dashboard being introduced soon. You're supposed to be able to view this data there, so why let anyone else have free access to it?
