Problem with memebership plugin...suscriptions have several issues

HI there,

I'm using membership plugin but I have a few problems:

- Admin can't change status member from admin area. You can change it but after save the page, the status remains without any change.

- A cancelled user is not be able to register again with manual payment.. in his user area he has 'pending' status.. but admin can't do anything because it appears as 'payed'.. and I can't do anything
