Floating Social Pinterest problems

I have added the Floating Social plugin, but can't get the Pinterest links to work. When I add the "pin any image" link, it shows up, but won't add a count. When I add the regular Pinterest link, it doesn't show up in the floating bar at all.

In addition, the Facebook like button seems to work, but most of the other counters don't seem to count anything. (Twitter, LinkedIn) Here is the blog:

Ideas?

Another aside, when you go to the settings for this plugin, it deselects everything. The active ones are still white (and the inactive gray), but the check boxes are off. So if you want to add a service, you have to reselect all the active ones AND select the new one. That seems odd and nonintuitive.
