Hello there!
 
Read over what Dermot has provided, but also here are directions to set up your User profile correctly.
 
Hello there, welcome back!  
 
Log into the Console
Click your email address at the upper right
Select Manage User from the drop down
Locate the User Profile that you are trying to use with the iPhone
Click the Edit icon at the far right side of the line
Click the Access & Permissions tab
Set ALL permissions to Admin or Access
Look at the key code listed and make sure that it matches the key code in use on your computer and is not expired.

Thanks for the help but that didnt help.  All my settings were already set as admin and access and the key code is fine.

I would suggest that the best solution will come if Support then take a look at what's wrong on the back-end, unless there may be any other ideas? Submit a Support Ticket
