URGENT MYSQL HELP!!

Hello, I turns out I accidently over wrote my MySQL user table and now everything is out of wack. I overwrite it again with a backup install of MySQL and it's working...somewhat.. When I try logging in through phpMyAdmin (it's a hosted site with ssh access) I get this error: MySQL Connection Failed: Access denied for user: 'root@localhost' (Using password: NO) Funn thing is I made the table user have a user with roo, no password, and all that. If you can fix this yourself or walk me through it I'd be much obliged!! I need help ASAP!! I'll email you the ssh account settings once you reply. Thanks, Stephen Craton http://www.melchior.us
