Macleans magazine download

I have an HP 32bit Windows Vista Computer......

I have an Adobe Digital Editions library  where I store ebooks for downlading on to my Kobo Mini and Kobo Aura eReaders when needed.

I have a current subscription to Macleans Magazine which I receive weekly via Canada Post.....

I wish to download these Macleans digital issues to my Adobe Digital Editions library so that I may read them "On LIne", and download them to my Kobo eReader when needed.

A "Step by Step" help by anybody out there would be greatly appreciated...........Thank you
