freitasm: The email address is probably the keyboard adding this.
Are you connected to WiFi? Can you visit the Withings website and login there to see if it's all working? Perhaps your ISP is having problems?
I've sorted the email address issue, and I most definitely have an internet connection.
I can visit the Withings site on my phone and login to my account.
I have logged a call with support but I expect it will be a few days before I hear back from them.
This is tremendously frustrating.
