can anyone help with the following message? i did the download and auto install are instructed, added the login block to my page and got the following...

Fatal error: Cannot redeclare class LoginBlockController in /home1/apicella/public_html/apicellaweb/packages/login/blocks/login/controller.php on line 54

where did i go wrong? after leaving it for awhile, i came back, logged in as admin and went to the page and there was a line of copy telling me i was logged in. left the page and came back and got the fatal error message again.

thanks,
greg a
