2 Daily Counter Porbs/Questions

Hi!

I want to set up the daily counter to use my MySQL db as it is used for other stuff as well. I've create dthe empty db and edited the config file with server/fb/log/pass info, but when I run the php file to create the tables nothing happends. I get no error message and when I check the database it's still empty, no tables.
What am I doing wrong? I'm using MySQL 3.23 under WinXP with Apache 1.3 server.

Also:

How do I reset it each midnight so only users visiting after midnight will be shown in the Visitors.php ?? (Can I also set a maximum number of visitors to be showed?).
