Why can't I add anything to my favorites?

My Mom and I used to share a Instructables account, but then she made me get my own. But when I went to add some recipes to my favorites, it said I needed to upgrade to PRO. I didn't when we shared an account. Why now?

EDIT: Now I can't view all the steps of an Instructable on one page. Before, I just had to be logged on.

The old account is grandfathered in for some of the pro features.  New accounts have to become a pro account to get those features.

I didn't know that having favorites was a pro feature though.
