No need to double post.
All you have to do is download the original Feralheart, from there you have to move your characters to Bonfire Island if you want to switch to Feralheart+.
When you appear in Lonely Cave you go go through a black portal that leads to Ficho Tunnel, keep runninng through the tunnel and you will appear at Bonfire Island. You can then log out and start playing Feralheart+.
