Geeklog Forums

Hello, I am trying to install geeklog forum (http://www.geeklog.net/article.php/20041016113244817), I uploaded all the files, Ienter the plugins part at the geeklog website, choose to install the forum, it directs me to a page where it says "The Plugin is Not Installed" and I have an install button. I click at the button and nothing happends, the forum is not installed. I checked the error log and there is nothing there. Does anybody know what the problem?

Is forum listed on the plugin's admin page as installed?
What's the URL for the page that says "The plugin is not installed"?
