Another mysql question
 

Ok i have read threw all the manuals on the mysql site but for some reason it dont want to work. this is what i have done.
mysql> GRANT ALL PRIVILEGES ON *.* TO MYUSERNAME@"%"
-> IDENTIFIED BY 'my_pass' WITH GRANT OPTION;

mysql> FLUSH PRIVILEGES

but when i try to make databases in this program (mysql control center) it gives me access denied i am lost on what to do here.
