My profile didn't load?

So I logged on tonight and found that I only have 15 points and my profile has changed up? I don't know what happened. Can someone explain.

Can you be more specific? For instance, how did it change? And why does it matter if you only have 2 challenges done? ;)

someone got your password and did challenges for you. i would advise using the lost passowrd function to create a random password for you.
