Then I too would be very unhappy over the after-sales services... some sw makers work like that (TBS owner is one), once you buy it, you ARE now one of those in the bag

... after buying TBS and see the owner turn a good sw into an experimental tool that has more bugs in every new update and the working version disappears forever

. You will never again turn back to a working version in their cases...
I stopped buying from such marketers who are all
sweet-talks during the beta version, but then the beta never becomes a no-buggy final product for months and years. As if their engineers have no idea how to do thorough bugs analysis and testing and leave everything to lady luck and the beta-users... On top, if the beta sw works on their high-end computers, then everything is all-right for them and the beta-testers' problems are no big issues... even if one of those problems are solved, there will be a few more new ones cropping up, and then more blah, blah, blah, and you get a new beta version# +1 ... I don't think the problem lies with the users' machines, it lies more in the faulty, rushed-up, bugged up, lazily-written code lines that only the users are supposed to test and report. Or why would there be so many bugs in such a small sw where the real core of the sw, the synonyms, is freely given by the users themselves. Writing a modular code around it shouldn't take months and years imho.
Come out with modules that really works, and then incorporate new modules under (strictly) separate test environment, without actually merging those under-test modules with a working module, just to show that the sw is now a all-in-one wonder, which incidentally is not! Why break everything more and more that was once working?
I purchased Spinner Chief 2 more than one year ago and never received the license key. Well I didn't ask for it til now but 1 week ago I decided to try it. The guy asked me to pay $50 for upgrade to 3, but I said first I want to try what I already paid for. The reply was exactly this: "
ok, so what is the problem now for you?" and I asked again and again for my license key which I paid over $100 but I think I got the guy upset for not upgrading
