[Plugin: Counterize II] Division by zero in ….. How to solve?

Hello! I am using the newest version of Counterize, and version 2.7.1 of WordPress. First when I manually installed it (I can’t install plugins automatically because of WP FTP error…), it told me about missing tables. I spent almost one hour creating them by myself. But then it didn’t say about them anymore. But now I have another problem. All around the statistics panel of Counterize, I see this text: Warning: Division by zero in /home/jupstejuho/htdocs/wordpress/wp-content/plugins/counterizeii/counterize.php on line 954. So what the heck should I do to remove that? It is annoying, I don’t know yet, that is Counterize even working properly. But hey, what should I really do about that?

Really, really big thanks in advance to that one who’ll propably solve my problem, I give you my respect and gratitude.
