O boy!! This is not good.. Need Help

[KOM]

Ok, I installed this hack that let's you look at pm's. So I go in and give it a test try.
and it missed up my DB.

So now the links at the end of VB like Contact Us - Admin - Mod - Archive - Top
Mod and Admin don't work it just go's to the main page of my website

if you go into the fourms and hit a users name and then try and hit User Options
it give's a ceazy like and go's to the desk top.

Ok so I go into Import & Maintenance/Repair / Optimize Tables
hit all, and then try to repair then no go. it fixed a few of the links like (Archive - Top-Contact Us) but the admin , mod , User Options are all busted up and not working and going to the main page.

Now I backed up my DB like 2 days go and would like to uploaded back to the DB.
the only thing is I not 100% sure how to do this. And if I get it to work will it fix my DB back to the day it was b4 ????

some one please help me out here
