you don't need to do it via "browser monitoring" normally with the store (my account .. hover over the link.. copy the link location.. with right click.
then go over to FDM and use the "+" icon.. IF the download window isn't show.
some websites will stop multi-part threads, so it doesn't work with everything.
just tried it in my account, works fine.. I'd suggest downloading at night there in the US.. and set FDM to switch off the pc also.
but via the web page it re-directs.. so I guess only via "browser monitoring" you get the 2nd link
