Do I need to be online to access PresentationPro PowerPoint designs?

PowerDesigns 5-in-1 Package > Pre-Sales Questions
An online connection is required to browse and download content. You can apply designs to your presentations either through the Express plugin for PowerPoint or by downloading your designs through your account.
Once a design is downloaded or applied through the Express plugin, an online connection is not needed to continue using it. 
 
You also have the option to purchase a 32GB flash drive with all content from your order pre-loaded onto it.
