As you stated above have you entered the commands properly?
Click "Start" then "run" then type:
Code:
C:\mysql\bin\mysql -u root peq
after that type:
Code:
GRANT ALL PRIVILEGES ON peq.* TO eq@localhost IDENTIFIED BY 'eq' WITH GRANT OPTION;
You should not need to add the 'mini'/'mini' user/password if you used Cavedude's installer as it does it for you.
