No post voting stats in WPMU dashboard

I have a WPMU install and I do not have the post voting stats plugin network activated.Some of the child blogs have activated and implemented the post voting stats plugin. Users are able to vote and are able to see the voting stats on the front end of the blog. However, when we look at the child blog's dashboard> post voting stats, no data loads, even though users have voted. What can I do to view a report of all post voting plugin activity?
