Slimstat partial data

I installed the latest version of Slimstat but I don’t get all of the analysis. Specifically I don’t get the pageviews chart, recent search terms, top search terms — but I do get the others. I did get the pageviews chart once, and sometimes get the top posts data and sometimes not. The number of view which is supposed to be listed beside each post in the list is always zero. What’s going on here? I upgraded from an old version through ver 3 to the current one. Did something maybe get lost there? Also, I started a new data series, but this was a month ago and there are almost 11,000 records — most of them not people of course.
