Amazonas Gem Publications


For anyone who has ever worked on a computer or surfed the Internet you know that strange things can sometimes happen. A file is fine one moment and seemingly inoperable the next. We live in an age of different file formats, different operating systems and different servers and while in the ideal world they would all compliment each other, in reality, they often conspire against each other. We want you to enjoy your digital publication but we also appreciate that in this technological age, things sometimes do not always go according to plan.

The links below are designed to help you with any issues you may have, however, if you do not find a solution, please contact us immediately at: Our customer service is based in Spain so please allow for any delays due to time differences.
