Found this when I was googling to find a way to edit the HoF (I had 600 odd when I had to format my PC, managed to salvage the save but forgot the HoF) and thought I'd point out that the HoF file is actually in public documents, so if you go to your C Drive, Users, Public, Public Documents, SI, FM10, and there it is.
Not from me just copy from Sigames forum from someone else.
I think if you delete that file everything will be resetted
