Help with mysql backing up (navicat)

Im trying to connect to the DB through Navicat to backup my Database. Well i put in this

Connection name:rafsdb1
password: its right i edited

It says im not allowed to connect to the Mysql database. What do i do? Is there an EASIER way to back it up?

After loging in to phpMyAdmin,
Go to the database.
Click export, and select the tables you want
Scroll down, and chack "Save as File"
Then click go.
A box should appear prompting you to download the file.
