What's the url to the site?

I'd be pretty confident you don't have the forum id's right but I could be wrong. Make sure you've set what forum id's you want the mod to opperate in. eg this forum on KWWHunction (Webmaster Discussion) is forum id 16
You can see that from the 16 at the end of the url
Code: 
http://www.besthostingforums.com/forumdisplay.php?f=16
If you haven't set any forums to check it won't check. You'll want to add the forum id's for the download areas.

If your sure you have the settings right then post a screenshot of the settings so I can see how you've set them.
