User Role Issue

Hi, this plugin is solving my problems. Thanks for great plugin.
The issue I am facing is with user roles. I want my editors to view/ edit/ and make changes to only this plugin. I was only using native WordPress roles. For the sake of roles I added role manager plugin but still unable to add capabilities for this plugin only. As through role manager I was not able to show this plugin to my editors.
I tried this plugin’s internal role based access. By default it is for Admins only. I assigned this to editors but after doing that the plugin completely gone form my admin menu instead showing to editors with limited capabilities. Then I deleted all stuff and install plugin again to view as admin.
The corn of this capability is admin no more grant or deny access its users access even cant see in admin menu. Please help me to resolve this issue. If I need to do some customization inside plugin file then guide me I will try to do it for now.
