I uploaded this and it was killed by the move to torrentguy.
The following should help
the following url will take you a page in isohunt which has all the 3 seasons separately so you can d/l all 3 at once if you wish all seem to be well seeded
season 1 is 11th down on page
season 3 is 9th down on page
season 4 is 8th down on page
if don't know how to copy and use this let me know. Apologies if you do!!
