I got the same message, which seemed a little suspicious. I've only downloaded a couple of freebies from them (including this latest one), but you do have to have an account and be logged in to check out on their site.
Instead of clicking the email link, I went directly to the 2bplayed.com site and tried logging in, and got a message that my password was indeed "expired". I followed a link on the site to reset it, got a second email, followed that to change my password and could log in again. So the original email seems/seemed legit -- but it makes you wonder if 2bplayed may have had a security issue on their end recently.
