A question about accessing the onscreen keyboard

I am frantically trying to access content on Broadway HD that will disappear after today. I tried on my PC, but the buttons won't activate. So I thought I'd try on my phone. I'm told by the web designer that it's all pretty standard; so I ought to be able to do this. (In fact, if I had an apple TV, I could watch it using that, but I don't.) I can find the fields for my username and password, but I can't seem to activate them so that the keyboard appears. There's probably some very basic piece of information I've forgotten. If any of you can help, I would be most grateful. If I can't do this soon, I will miss the broadcast as it will disappear.

Try to activate the username field by double tapping it. Do the same thing for the password field. If it doesn't work for the first time, delete and reinstall the app.
Hope this helps.
