Blank settings page

I Installed the 1.0.3 version of WPMU DEV SEO and I just get a blank page in the Step 1,2,3,4 and 5.
The page only has a "Save settings" button (And it works! so I have a "Settings save message every time I click on).
I have WP3.1 and everything is updated to the last minute (I see the doubled name of the blog issue other member wrote before; maybe some debris froa All In One SEO pack)
