My Cloud App

When I try to acess to My Cloud App, the app asks an e mail and a password. I try to sign with the e mail and password that I register on the website, but I can´t acess.What´s going on?My Cloud app doesn´t have a alternative to register and then sign.

Which app, the Desktop App? Are you able to provide an image of what comes up asking for email address and password?

I needed a code. Everything is OK, now!
