I downloaded and installed SugarSuite-3.0.1b, For first time installation, everything was smooth. I tried to reinstall for second time due to improper configuration previously. I simply deleted the folder and database located at Apache/htdocs and mysql/data and ran the installation and the following error message came out:

Creating the database sugarcrm on localhost...done
Unable to select database: Access denied for user: '@localhost' to database 'sugarcrm'

Please help me to solve this problem, Thank you.
