Groups 404 Redirect

Hi I’m using the groups 404 redirect and redirect for categories. When I have a protected post and someone is not a member of a group, it automatically sends them to a 404 page instead of the page I indicated for the page redirect.

Here’s a post

Here’s a page or a category listing

http://www.learningguitarnow.com/premium/all-access-area/

I modified the 404 page to not say 404 until I can find a fix.

Is there someway for posts to go to a particular page just like the page or category?

Thanks!

John
