creating a connection

Hello. I am using the Extract Sentiment operator. I input some Tweets and it worked fine when I used vader or sentiwordnet. I am trying to get Aylien to work. I choose from the menu options, Connections>>Create Connections. For connection type I selected Aylien and Local Repositor and created it. I registered at Aylien and got an app_key and app_id. But when I try Test connection it says: No test performed. Then when I set the parameters on the Extract Sentiment operator, I need to enter a value for aylien connection but in the drop down box there are "no suggestions found". Does anyone know how I can fix this? Thank you.

    The column you want to analyze is called 'text' in your excel? 
    If not the operator will indeed not provide anything, as this is the attribute it needs. 

    Also, not sure if the aylien operator expects the attribute to be in text format (so not nominal), so better check that also.

    I had the text field filled in. I received this email from the company
    "I'm afraid that we have deprecated the Text API product and stopped taking on new users over 12 months ago. So unfortunately we can't help unless you are looking to use or subscribe to the News API, our core product.

    Note, I manually typed in the name of the connection in the aylien connection field. Here is the log info:
