Maybe I am wrong.But please try the following:
1.Type mysql -u root -p [password];
2.Type create database [databasename];
3.Type show database; <-To verify the new database has been created.
P.S. My friend,you can simply download MySQLCC from the MySQL website.It is a GUI software to make you work much more faster than typing command.
If you have any further problems,please post here.
