Redirect Problem !! Major Issue

Hey Guys,

I am in deep trouble. I had integrated bbpress 1.0a2 with wp 2.6.3.
I referred to this solution to get bbpress & wp completely integrated.

i had edited pluggable.php as given in the above link & wp-config.php

But when I pointed to my website, ever since I have been getting redirec-loop error in firefox.

I replaced these 2 files with the backup I had made but ff is still giving me a redirect-loop error. (the browser gets automatically pointed to wp-admin/install.php)

Please help guys,
