Moset tree plugin - not " working"?

HI,

i have installed the free moset tree plugin which display only the author pictures under the mosets tree listing. It actually displayed the name of the author just below the listing. That is cool. However , up on clicking, the name does not direct to the person profile page ( it looks like a link and i expected that). does it require to install the payed mosets directory app too to do that function alone?

Regards
