Error connecting to database server

[doubledi]

Hi,
i'm trying to install TW v0.353, but an error occurs:

Error connecting to database server
File: .../twatch/base/db/Db.php Line: 193
ArdeDb->connect( )
called in File: .../twatch/admin/install.php Line: 38
TwatchInstallPage->init( )
called in File: .../twatch/base/lib/Page.php Line: 22
ArdePage->render( object [ArdeXmlPrinter] )
called in File: .../twatch/admin/install.php Line: 187

Any Ideas?

Thanks

Double check the database settings you are using (server, username, passwords,... )

the db settings are ok, localhost or 127.0.0.1, user and password.
