-Subscription Plans and Access Levels DO NOT SAVE!!!!!!

Just installed Memdership ($39)
-Subscription Plans and Access Levels DO NOT SAVE!!!!!!
-I press save and when screen refreshes I get this:
No Subscriptions where found, click above to add one.

-This plugin is ABSOLUTELY USELESS if one cannot save these items.
-Any ideas before i ask for a refund?....?...
