Password unable to change after migrating site

I migrated my site through to WPMU hosting last night and my password is now not working on the login page. I have attempted to reset the password through phpmyadmin but that doesnt seem to be working either. The wordpress lost my password link is taking me to a 404 page so im not sure if the migration worked fully but is there anything else I can try?

Fixed: Got it to change through FTP a couple of minutes after posting.
