Does your MySQL root password contain special characters? Then you should change it. Special characters have caused problems in the past (there are some threads about this in the forum).

You can't populate it manually. Please remove the empty database and the directories /root/ispconfig and /home/admispconfig and install ISPConfig again.
That's good because you can't install the SQL dump manually.
