Drigg Admin Drigg_Promotion Missing

I seem to have broken my Drigg admin section a bit and I need some help. I've been trying to get the Radioactivity module to promote my drigg scoops and it hasn't been worked yet.

So, I was thinking I could look at the promotion module and understand the logic and hack something to get it to work. Well, it still didn't work and I had backed up the files before I made any edits and I uploaded the original drigg_promotion.module file to the site and thought everything was ok.

The problem now is that the drigg_promotion no longer exists in the Admin interface. The tab is missing from the Drigg Admin secton and if I try to get to it from the URL directly it takes me to the first screen of the Drigg settings like the Promotion doesn't even exist.

I'm really in need of help. Thanks!
