Membership Levels not Saving

I got the WPMU membership plugin through app sumo. I have it set up on localbizseobook.com. I'm having trouble with the subscriptions tab in the backend. At first it wouldn't read any changes I made to my existing subscription level. I then deleted my existing subscription level and now I can't save any subscriptions.

Because of this my http://localbizseobook.com/welcome/
http://localbizseobook.com/subscriptions/
are not showing up at all.

any help is appreciated thank you
