Cannot log in

This app seems like a great idea. One problem though, I cannot use it. I tried logging in with Facebook and it keeps saying you have already made an account. Then I tried to use my email to make an account. That didnt work either. This app is like a a diamond ringgit locked in a vault. It has great potential, but its worthless until I can use it.
