Sadly you will have to reinstall the game again for Windows 10, there is no way around this I'm afraid.
I remember when I updated my old laptop to Windows 10 it said that all my files were where they were originally....yet a bunch of the stuff I had installed no longer worked. There is definitely something fishy with the automatic updating to Windows 10. So it could be that the directories aren't quite named the same as they originally were which is definitely annoying, and concerning.
