Paying for the free version of Membership?

Hi,

I'm a subscriber since May 2013 and I have been paying €9.00 a month since then. I have not moved from Membership to Membership 2 (as my installation suggests) yet.

I have some questions.

1) Am I currently paying for the FREE plugin? My WPMU DEV account says I'm a "Membership Pro" user, but the link to the product is broken.

2) On the Membership 2 Pro webpage the button says "Upgrade to Download". Am I not eligible to this version with my current monthly payment? Need I pay the price as a new user?

3) Can Membership 2 Pro be installed on any number of sites?

Thanks for your support.
