No final da instalação dá o seguinte erro:

Warning: mysqli_connect() [function.mysqli-connect]: (42000/1044): Access denied for user 'bigxpicanha4'@'200.234.200.175' to database 'sugarcrm' in /home/bigxpicanha/public_html/crm/include/database/MysqliManager.php on line 284
Could not connect to the database. Please refer to sugarcrm.log for details.

Ele não consegue acessar o BD. O que fazer?

obrigado
