So if running the game as administrator didnt seem to work and if the save files are the issue then what would should do? I tried redownloading it too but that didnt work either.

You can go to your user folder then \AppData\LocalLow\Necro Bunny Studios\Rise of the White Flower. You can just delete the Rise of the White Flower folder. But if you want to keep your saves, make a backup of it, run the game, then merge the two folders together. When it asks you if you want to overwrite the files that are already there, say no. That should solve the problem and allow you to keep your saves!
