I am at the same time inclined to be sympathetic to them (since you searched out an unlinked legacy page on their web site marked 2003-2006 and then insisted that they support it) and sympathetic to you (since their terse replies were indeed assholey). So I don't know what to say.

"What interesting logic your email contains."
"As said, the SE Edition is discontinued. Stop nagging now, please."
Perhaps they assume that since their main web pages no longer link to the product or the hidden password page you found, people would get the idea that the product is unsupported. Who knows. A user at
http://blogs.msdn.com/b/jonathanh/archi ... 39645.aspx confirms that their support was always bad.
So this is why I always prefer open source, or at least truly freeware solutions rather than closed source, shareware, trialware, or DRM-Light password request schemes. It (mostly) doesn't matter if the developers turn out to be scum if you already have the code.
