Sometime, I'm assuming realtively recently, Family Echo changed the limit for how far people can added from the "Founder" of the tree. I would reccomend making a complaint through the contact form. This truly is an awful change, as one of Family Echo's best feature was that they were limitless and simple. The FAQs says that this is in order to provide privacy for distant family members, however Family Echo already has a pretty secure sharing feautre, as there is no way to remotely access any other family tree without it being shared first.
