Lost Password script doesn't work?

[Narkissos]

Hi all.

I recently converted from SMF to vBulletin.

Since converting, none of my users' passwords work... So, as suggested in the vB manual, I sent out a couple mass emails requesting that members re-set their passwords: http://www.vbulletin.com/docs/html/impex_passwords

A large percentage of my members tried to re-set... but none were able to.

I, a non-admin account, attempted to re-set my password... Nothing doing.

Since, I've had to manually re-set each member who emailed me requesting it.

A number of them didn't bother to email me.

It's been a frustrating issue to be honest.

Does anyone know how I can possibly rectify this situation?

Thanks.
