Link for first topic "Click here to create a new topic" doesn't work.

Hi,
I installed today the plugin "Forums" on a wordpress 3.5.1 with theme "Progress Wordpress for Business" by Artem Shashkin bought on ThemesForest.

After I installed the plugin, the link "Click here to create a new topic" to create the first topic open the Homepage of my website without any options to manage the forum.

Thankyou
