Major help needed!!!!!!

I recently changed wordpress address and url, improperly. I was locked out of my site, but solved that problem.

I have a new problem.

For some reason most of the links on my site, link to the root domain of my website.

my blog is http://www.ileasebeats.com/beabetterproducer

but for some reason most of the links forward to

http://www.ileasebeats.com/index2.php

Does anyone know how to help me with this?! I was just having some of my best days traffic wise lol, then i get this!
