Hello and thank you for such a great plugin.
I have been using plugin organizer nicely with s2members, but after the last update to plugin organizer my s2members plugin stopped working when my members had to download.
It also seems others are having the similar trouble and s2member requested that we speak to the developer of plugin organizer.
Here is the link to another user of s2member having trouble: http://www.s2member.com/forums/topic/mebership-level-doesnt-upgrade-automatically/
Thank you very much for your time.
