It complains about an object group there, and it's the animals one as you can see, I don't know why, but it could be because you have several copies of it, or installed the map pack several times without any luck, maybe even some other mod installed?
To be really honest I don't know, but I know for certain that there's nothing wrong with the map pack installer from here
http://feral-heart.com/index.php?option=com_content&view=article&id=23&Itemid=40All you really do is download the the torrent file, run it with a torrent program, make sure it's 100% run the .exe that the torrent program downloaded and you're good to go.
I installed the maps just recently to see if anything was gone, but it worked all fine for me and I did nothing different.
If you did this correctly and it's not working, I'm not actually sure what you're supposed to do. From the logs there it says it cannot find the object file animals, and the exe does in fact place them correctly from the star. It's like something or someone moved these files, or they were never written into the FH folder in the first place.
If I were you, I'd just redownload and reinstall the map pack, if not luck, just do the same with the game and then the map pack. But that's only if you really want to go through the hassle to get those maps.
