When you see the message 'Enabling or disabling Online Features requires starting over' it means that your internet access is disabled within the software.
In order to order your project, you will need to click the lightning bolt in the top right hand corner of the sofware and tick 'Enable Internet Access' and then 'start over.' Don't worry you won't need to start your project again, just ensure your project is saved before clicking 'Start over.' (if it isn't you will need to start again so this detail is rather important!) You will then be taken to the home page where you will be able to re-open your project and order.
