Joomla! Template LT Spa - Item Support

Hi, I just installed the LT Spa Theme but cannot connect to my database.

http://perfectbeautylounge.com/

"Error displaying the error page: Application Instantiation Error: Could not connect to MySQL.?

Here's my database info:
Database Name: perfectl_beautylounge
Username: perfectl_joomla
Password: o&6*tu[ocT%$
I know it's the error message for SQL. The database information is correct.

Where do I go back to fix it?
How do I reset the database connection?
