wp-config.php/NotifyMe Mailing List Plugin Help

Hello,

Today I installed the NotifyMe Mailing List Plugin (http://www.naatan.com/?page_id=95). Its information is in my WordPress, but when I try to test it out (http://backtoworkrecords.com/?page_id=26), I get the following message: There doesn’t seem to be a wp-config.php file. I need this before we can get started. Need more help? We got it. You can create a wp-config.php file through a web interface, but this doesn’t work for all server setups. The safest way is to manually create the file. (http://www.backtoworkrecords.com/wp-content/plugins/notifyme.php).

However, I DO have a wp-config.php file, and as far as I know, that file has all of the proper information in it.

Any suggestions?

Thanks in advance,

Warren
