I am unable to access WP-Admin as no username or password will work

I am hoping that you can help because my host service and WP forums havent been able to figure it out.

I was working on my site: http://randyjcreative.com and it logged me out all of a sudden. I tried to log back in and it would not allow it. I tried to reset my password but it gives me one of several errors which I have attached and then it prefills username as 'undefined' and it tries to log-in over and over until WP stops it.

I have tried resetting the password through php using a MD5 number and no matter what, it tells me [Login Failed Sorry..! Wrong Information..!]
