well, thats clear.. but I got it to work.. strange.. heres what I did.
I first installed FH at about patch 1.6 I believe, then I downloaded Feralistic, which kind of concludes that if you install it using a ''older'' patch, it works... but.. then again this doesnt really help anyone, since I wouldn't know of a way to the game with an older version... guess waiting for an update of Feralistic is the only option
