For subscribers who are using SlideMagic to download PowerPoint templates only: I have re-run the conversions of the entire database to solve some issues with arrows not being rendered correctly. All should be working fine now, let me know if you still find a slide that does not download correctly.
Pro-tip: try the SlideMagic app, a much more convenient way to work with the template database, convert to PowerPoint (if needed) as the very last step in your workflow.
