You have no my_preset file?
In that case, you should probably uninstall FeralHeart and delete the FeralHeart folder (make sure you do that). Then reinstall FeralHeart, and all the folders should be present.
I remember I used to not have an Exports folder, but once I un and reinstalled FeralHeart, deleting the FeralHeart folder beforehand, I then had one.
Hope this helps.
