Downloaded and doesnt work.

I downloaded this to avoid having to get a money order for my rent every month.
I try make my account, select where I live, go to login and it tells me "missing address1"
Doesnt show whats missing. Doesnt tell me where to go of what to fix.
This app would save a lot of people a lot of time. Please fix.
