Download Videos of a Premium Course from Online Secure Platform

Purchased a Premium Course online but there are issues of internet and network in my area so I need to download the contents. However, I am unable to download the contents to my pc using IDM (Internet Download Manager) or any other software or addon for browser. The contents are hosted on CloudFront. There are a lot of videos to be downloaded. If you can help me find a way to achieve this. I am ready to pay a premium amount and We will finalize the fee and all but if you can help me please let me know!
