Verification Email isn't working, i think it's the hacks

I've installed . . . like 20 hacks on my forums if not more and the email verification system won't work! If a new person wants to regsiter, he fills the form, it's all good, he gets the email notification, he clicks the link to verify it, but he can't login in! it says his password is wrong. I'm thinking somewhere along the lines of something being wrong with register.php in the last part of the file so someone PLEASE PLEASE PLEASE help me because after this, it'll be the end of my blasted problems! Also, i don't really wanna replace it with a unhacked register.php because all that stuff i've hacked into it won't work and only god knows how many i had in their, i definitely don't remember them all.

Btw: I posted this at vbulletin.com and they told me to come down here cause my forums hacked.

This is the last part of register.php that i currently have:
