IB not listed as provider when setting up connection

[enhancer]

I have a SIM ninja acct and want to connect with Interactive Brokers paper account also.
I have followed the directions at the link http://www.ninjatrader.com/ConnectionGuides/Interactive-Brokers-Connection-Guide
but when I go to step 9. , I cannot select Interactive Brokers as my provider because it does not show up in the list.

help please
