ok, since you have already made the config, i guess you took the win32-noinstall-b3-version.

so i just explain the mysql-configuration:

1) install XAMPP
2) start apache/mysql in the control panel of XAMPPP
3) go to http://localhost/phpmyadmin
4) create datebase named B3
5) open BigBrotherBot-1.8.2-win32\sql\b3.sql and copy the text in clipboard
6) in phpmyadmin click on "SQL"
- paste your clipboard in the textarea
- click OK
7) the hardest part (mysql) is finished now, just enter your mysql-data in b3-config and start the win32-noinstall-version of b3

tell me when you got stuck
