Can't Login To WP Sites

I have a problem with a couple of my wordpress sites. I can't login to the backend of both of them. Also, when I do forgot password, it doesnt recognize my email. Please tell me how I can fix this problem and I will pay $10 to whoever can help me fix this. Of course I still have full ftp access, but I dont know how I can fix this problem through ftp access or the control panel, but I do still have access to both. ## Deliverables 1) All deliverables will be considered "work made for hire" under U.S. Copyright law.
