Error when installing Coppermine

[FIRARO]

I have installed Coppermine and ittold me that registration was successful.
When I navigate to the url I get the following error found in this page:http://dr-firaro.info/gallery/

Fatal error: 

While executing query "SELECT * FROM cp_config" on 0

mySQL error: Table 'fero_cpm1.cp_config' doesn't exist

Well, then the database doesn't exist. Use a tool like phpMyAdmin and browse your database to see if the coppermine tables are there. Make sure that you haven't put a dot into the table prefix during install. If you have done so in error (put a dot into the table prefix), perform a fresh install by deleting include/config.inc.php and include/install.lock using your FTP app and then running the installer once more.

I did as you told me and I saw that the tables really don't exist.
I am wondering why they don't.

perform a fresh install by deleting include/config.inc.php and include/install.lock using your FTP app and then running the installer once more.

pay attention to the database connection settings. be sure to enter right datas without dot in the table prefix or in the database name for exemple...
