Passwords do not work

[tuggy24g]

I converted my forum from Phpbb to SMF and now when ever I go to my forum my members passwords do not work. There username work, but not password. They have to reset them inorder to get on the forum. Not sure how to fix this problem, but if you can help that would be great!
