Although this is a very old issue (sorry didn’t notice it), however…
In case anybody else experiences the same problem of the counter not displaying at all, the cause will either be a problem with the version of jQuery your WordPress is using or a javascript clash with another plugin.
First check that your WordPress is up to date and update if necessary, and you have no other plugins installed that may be replacing the jQuery version. If you still have problems please feel free to contact me with a url of where you think a counter should be showing and I’ll be happy to point you towards a solution.
