Unable to connect to MySQL database

Hi there,

I need some help, please... I have "installed" the Uniform Server Zero XI 11.3.3 on my C drive and add my joomla site within www folder. However I wasn't even able to install joomla for I got the message: Error displaying the error page: Application Instantiation Error: Could not connect to MySQL.

I have created a new mysql database and imported the site's database into it. Also I have modified the paths for logs and tmp folders, the database name and user in configuration.php. Nothing else happened.

Please advise. Thank you.

The MySQL error log is as follows:
