Hi, 
	I'm totally new in this, anyway I have downloaded th sample file for unity and I have passed the API key and secret key in constant file. 
	 
	when I run the file in the unity editor I got many buttons, I tried to click (create user) but I got this error
	 
	App42Exception: EmailAddress is Not Valid
