NTFS doesn't work on leopard

[mackerman93]

Last month, I could mount NTFS partitions in read-mode, so I tried a program called Paragon NTFS, so I could use write-mode. It did work, but when the trial expired, the NTFS partitions didn't mount. The guide said that I had to uninstall the Paragon software, and so I did, but once I rebooted, I still couldn't mount them.
If it's of any help, when I try to mount the partitions in Terminal, this is what I get:

iMac:~ mAckerman93$ sudo mount_ntfs /dev/disk0s3 /Volumes/Vista
dyld: Library not loaded: /usr/local/lib/libUFSD.dylib
  Referenced from: /sbin/mount_ntfs
  Reason: image not found
Trace/BPT trap

From this I think all I need is the file libUFSD.dylib, although I don't know where to get it.
