Password Reset Will Not Work

I have tried every way that i could find to reset my password. I used the “forgot password” link and it sends me the email but that password still doesn’t work. I also tried the emergency script to reset the password and the new password does not work. I then tried the myphpadmin method and the password that i specified does not work. I repeated all methods numerous times. There must be a problem with my database or wordpress instillation. I am trying to avoid reinstalling my blog. Please help
