Your "mega", as in the downloader Megasync?
It's basically just for downloading when you hit the download button from the linked page.
The links work just fine in a browser.
Proof -
Try downloading as normal download instead.
Hover over the downward arrow, select normal download.
:EDIT:
Also, don't just quote someone twice to say two different things in two consecutive posts.
Just edit the first one to add more, they'll still have a notification that you've quoted them. Unless you're on their ignore list, at which point they'll never be notified at all.
