Can Someone Help Me Figure Out How to Get SilverStript going

Warning: mysql_get_server_info() [function.mysql-get-server-info]: Access denied for user 'ODBC'@'localhost' (using password: NO) in C:\Program Files\xampp\htdocs\silverstripe\install.php on line 77

Warning: mysql_get_server_info() [function.mysql-get-server-info]: A link to the server could not be established in C:\Program Files\xampp\htdocs\silverstripe\install.php on line 77

And I did have An Error on the INstall.php ln 354 but I Mad ethe Function always Return true,

Hmmm I thought I had It says the database details are all good

On The SIlverStripe Installer:
MySQL server: localhost
MySQL username: root
MySQL password:
MySQL database: nath

And From PHPmyadmin DB Nath

root localhost global ALL PRIVILEGES Yes

I Havn't got a password on the dB could that be the problem?

And Also this Line at the Bottom of the Screen.
mod_rewrite enabled You need mod_rewrite to run SilverStripe CMS.

Ok Enabled mod_rewrite in Apcahe Conf file, and gave the Root user a password now it runs, and also extended the memory limit.

ODBC? http://en.wikipedia.org/wiki/ODBC

Its basically a "compatible" protocol to talk to databases, but you shouldn't need to use this with SilverStripe. You can, for example, use this to get PHP to talk to almost any database (e.g. Access), but in my experience its not something you can constitute as reliable.
