Hi, I just bought the Community ACL

After viewing the nice demo site.
Okay I just installed it and I have a few things to setup, wanting to restrict a members access page now.
Anyways I don't have the User - Community ACL plugin like the demo site has.
I also have this message,
Community ACL core patch in the `/home/gtstars/public_html/dreamgirls2/libraries/joomla/application/module/helper.php` is not detected.
If you want control over the modules the patch needs installed.
You will need to manually replace the helper.php file with the one included in the CACL zip file. The web server doesn't have write access (rightfully so) to helper.php and it cannot overwrite the old.
Copy this file:
Community ACL.zip/site/joomla_patch.zip/libraries/joomla/application/module/helper.php
To:
{your Joomla! site}/libraries/joomla/application/module/helper.php
Community ACL plugin for Joomla! is not installed.
My joomla Version 1.5.20
Any help please
