I setup an account with articulate online. They have a 30 day free trial, after that it is rather expensive. If you choose articulate online when you go to publish, all that you need to do is enter in your articulate online account name and password. you can sign up here
Then when you go to publish your account url will be username(whateveryouchoose).articulate-online.com.
Then enter in your email address and password for your online account and thats it.
Once you go to the account url on your ipad you just log in and select the articulate file that you uploaded and it will automatically open in the player.
Hope that helps.
