Hi Suzieqb, maybe try in the Kobo Vox forum, and make your own thread with the title being a summary of the problem:

It would also help if you provided more details. What exactly are you trying to do, which steps are you taking and what happens when you do, and what is the result? I'm afraid I can't help you as I don't have a Vox, but I'm sure someone will be able to help you in the Vox forum. Good luck!
