Steve,
The US distribution of this product is now done by Noahji. Their phone number
is listed in the latest issue of one of the Amiga mags..I don't recall
which..at the end of a review of something else they distribute. I also have a
Retina and called them for the updated software. They quickly and happily sent
it to me but it cost about $25.
If you don't find the number elsewhere I'll try to look for it tonight when I'm
at home.
Bill
