I also think that there are some old files on your Mac.
Well, I'm not an expert about removing drivers and such stuff under OS X manually.
But I've found some links and suggestions somewhere else.
It seems that you have to delete some files manually. But make a backup of the files before you delete them - just to be safe.
Ok, here they here:
#1
1. Uninstall every NTFS Driver (Paragon, Tuxera, NTFS-3G etc.)
2. Restart computer
3. Delete /System/Library/filesystems/ufsd.fs (backup just to be safe)
4. Install any NTFS Driver, I used Paragon NTFS for Mac 9.01
5. Restart and enjoy!!!
