Alright, this is what I would:
1. Empty Recycling bin
2. Delete ALL FeralHeart folders, items Whatever, Look in everything, don;t leave a trace behind.
3. Make sure Recycling Bin has been fully emptied after deleting and all.
4. Uninstall FH
5. Restart Computer, to get rid of all the mingling particles
6. Re-Install Feralheart, and this time save it as (folder): FeralHeart!
