Sorry you can't contact JD13. Perhaps try JD14 from
www.hel-forums.com!
Anyway, look on the outside of the box you might buy. If it says 30002R then you're fine. If it says 39002 then you've got a problem until Messiah is cracked for this model. You might have to try more than one store - if there is such a thing in WA.
JD lives 250 miles from the nearest store!
