Allowing Access to Supporter Plugin to paid Members

I'm having some issues with supporter-plugins.php and supporter-write.php.

First not all of the plugins are available to paid members. I'm also wondering is there a way to make the supporter or membership plugin available to users because those plugins do not even show up in the list of plugins.

Second, supporter-write.php is not restricting access to "add new page".

Any ideas what might be causing the problems?

Thanks.
