Thank you for your post.
It seems that the ABM web site is no longer active. However, a quick search on Google found several places to download it.
404 error messages and dead links so far
I'll try some more, but it seems they all link back to the abm site and that site is down.
Update - Even going to the developers site (http://www.productivecomputing.com), they link back to the www.addressbookmanipulator.com site. so I guess I'm out of luck until it goes up again.
Okay, this morning I was able to get to the site. No idea why.
