I am trying to add a domain to my Blackberry, but it says I am offline.

You have installed the WiKID two-factor software token on your Blackberry and you are connected on your mobile network, but when you try to add a domain, you get a message saying you are offline and need to be online to create a WiKID Domain.

Try rebooting the Blackberry, check your firewall settings and make sure that you can access the internet via the browser.
