MarketBlast is dead?

Note: I've used MarketBlast, a PC/Mac Seller Mgt tool for use on eBay, for a few years, and was quite pleased with it's feature set, and robust abilities. However, on Nov 1st, my installation quit working correctly. In the ERROR LOG was an entry saying "Demo limit has been reached". I've paid for the program, initially on version 1.4, and at each time it has been enhanced: for versions 1.17 and 2.0

We have sent a total of seven email messages since Nov 1st, (there is no phone contact info available), and aside from an auto reply saying Acclivity received it, I have heard nothing from them.

So I have a program that I've paid a couple hundred dollars for suddenly going dead in the water - with no prospect of revival.

So now, it's onto Turbo Lister and Auctiva - both freebies, and useful apps; but like the demise of the original Sellers Assistant, the loss of MarketBlast is a pain in the butt.

If you have an alternative that you are happy with, please let me know about it.
