How to use Membership plugin with Upgrades plugin?

I want to use Membership plugin with Upgrades plugin.
But I don't know how to add Membership plugin to Upgrades plugin.

I use Supporter plugin.
But Membership plugin is very nice, so I want to get extra fee to use Membership plugin.

Please tell me how to use or
Is there any idea to do getting extra fee?

    Thank you.

    I read this thread

    and add following code to membership.php


    upgrades_register_feature('b46127d3c32de3d485a478e88b8f6593', 'membership', 'membership plugin');
    if (upgrades_active_feature('b46127d3c32de3d485a478e88b8f6593') == 'active'){
    //here is the membership.php original whole code
    // nothing

    * b46127d3c32de3d485a478e88b8f6593 is just a unique id.

    and move file to


    That's all.

    Sorry, I'm wrong.

    Membership plugin is displayed in the upgrades plugin list,
    but I subscribe the upgrade package which includes membership plugin,I got following error.

    Warning: membershipadmin::include_once() [function.membershipadmin-include-once]: Unable to access /public_html/domainname/wp-content/plugins/membership/membershipincludes/classes/upgrade.php in /virtual/wellfully/public_html/ on line 82
