Well. There is supposedly a later version that what you're trying to use. I'm not sure how its accessed. Though, I think it has to do with the where you saved the FH+ folder. Though I'm not exactly sure. However, even past this point, there are a number of bugs that come along with using it. It's honestly more trouble than it's worth. The player-count for that place is low, the maps lag meg-hard, and honestly, it'd be best to wait out until Simba puts out a later patch with all the bugs fixed.
This is just my opinion.
Make sure you have FH+ in its OWN folder on the C:Drive.
