Since we have built an entirely new platform from the ground up, we decided not to import any user details over from the old site. It's such a new build that we wanted a clean slate for only the people that wanted to move forward with the community. Sorry for the hassle, but you will need to create a new profile.
It's a pretty simple on boarding process, and you will understand why we didn't import profile over once you get into it. Hope you enjoy the new site and we look forward to seeing what you've been up to.
