Profile information not being saved upon account creation

Hi, I have the membership plugin installed on my site.

Profile information is not being saved upon account creation, when a user fills in the registration form, they go through the effort to fill in all the fields and when they login, there's nothing in the profile, just the username.

I've been having may issues with this plugin, it's perfect for what I need, but can't seem to get it working. The other issue is that if a member is already signed up and wants to upgrade their subscription, the subscription page shows the available subscriptions, but not the button to go to the next step!

I'm stuck, please help!
