[Plugin: WordPress Download Monitor] Links not working on default download page

First I’d like to thank you for this plugin so easy to use…

But I have a problem.
Well, with all default options, the download page give me links which reload the page but don’t display any category page nor single download page.
Whatever option of links I choose, there’s invariably links with ids and no effect when clicking on category or file. My .htaccess is fine and permalinks reloaded…

I need your help but I’m aware you need more informations… so tell me 😉

Thanks in advance.
