access denied to database

Hi, I'm a newbie so pardon this question. I can't get to my newly created database. At the mysql prompt I type in "use dbname;" and I get "access denied for user: '@localhost' to database 'dbname'" (dbname is a not the real name.). I'm following the instructions from right here at devshed, so I've got no idea what to do now.

P.S. I didn't create the database, my ISP's system administrator did. So a second question would be, how do I find out if the database is really there?

show databases;

See if your database is there. If it is and you still can't use

use your_db;

then they messed something up when they created your permissions.

Thanks SepodatiCreations. The database is there along with 7 others but I still can't access it. Hopefully the system administrator will fix the permissions tomorrow.
