Hello Arandomperson, download the game to a whole new folder. For example I have two versions of FH, however the one is installed into a file I named "Feralheart 1.17" in C:/. Sometimes when installing a new version, files will overwrite one another if they are installed to the same location. Try deleting anything named "Feralheart" in your C:/ drive and then go with a fresh installer.
EDIT: Someone else is having a very similar issue, leading me to believe this could be a real bug. I'd hang tight for a little bit until a staff member responds to your post in the bug thread!
