I keep getting the name of the database is not correct and can not connect into the database
This is the error I get

settings.php: line[133]
Could not connect to database "forgott1_roster "
MySQL said:
1102: Incorrect database name 'forgott1_roster '

If you use a web host, go to your webserver's control panel and into your mysql section

Make absolutely sure the database name you enter in the Roster install is correct

Next, you can re-install Roster by just deleting or emptying the conf.php file
