Our lessons are delivered as Zip files and they are large files so you have to make sure you're allowing enough time to download them. If you open the Zip file before it's completely downloaded you won't see all the video files. You'll need to extract the MP4 and PDF files from the Zip file/s to be able to use them and you’ll need software to do so. If you don’t have a Zip program on your PC you’ll need to install one to open the file. I use Peazip which you can get free, here. If you are downloading the file on an older iPad or iPhone, please read this : Downloading on iPads and iPhones PLEASE, BE AWARE THAT THIS LINK/S EXPIRE IN 24 HOURS AND YOU'LL BE ABLE TO DOWNLOAD EACH FILE A MAXIMUM OF 3 TIMES.
