After installing the Community updater that you hopefully downloaded and installed after posting your near identical thread about this, then you have to open up the community content updater found in your FH2 folder and select "community map pack". This will now download and install the maps automatically. I am unsure if you need a torrent program. If so then download Utorrent.
Note that I already have it, so instead of "remove" it shall of course say "install" or "download"
Congratulations you can now play new maps
(of varying degree of quality)
