We've used Proclaim since the beginning or pretty close to the beginning. I've enjoyed all the development. Today, tried to log in and post my sermon notes for the weekend and I'm getting a "Purchase Proclaim" type screen. You can see it gives me the option to sign out.

I'm running a Macbook Pro 10.11.5 (15F34) 2.5 GHz Intel Core i5 16GB Ram. Don't know if that helps or not.
