Adobe DRM protection

Hello!

I have just bought a book with an Adobe DRM protection, and while I was able to confirm my Adobe-Id on my Android, I was still unable to download the book.

When testing the same thing on my computer, it says I need a software to read the file/open the link. In all honesty, I don't know where to start, as Adobe is already on the computer and this just seams like a reeeaally difficult way of doing things and maybe it's just me, but spending an hour on getting past a license issue after buying a product is really annoying. And problem is still unsolved.

Help.
