Hi Kerry,
It seems there's a verification step to login Twitter(http://take.ms/lfyIs). If you have already created the app, you can enter the consumer key and secret here(http://take.ms/NSB1S) and save. If your app configuration is fine, you should be good to go.
Hey Kerry,
Glad to know that your issue has been resolved now.
As a gentle reminder, kindly start a new thread if you have any other issue in the future so it will be easier for us to manage your inquiry. I will lock and mark this thread as resolved.
