As a follow-up to this, today I experienced the same problem.  The
eQSL.cc site was returning an error code of 500 when trying to
download the list of Authenticity Guaranteed users.  So I disabled my
Internet interface (pulled out the cable) and tried the Updater again.
I got the same error code of 500!  Thus, when  a website returns an
error code of 500, there is no way for the Updater to distinguish
whether the Internet connection or the web site itself is the source
of the problem.

It may be possible for me to add extra code to indicate whether any
previous files were downloaded successfully, and if so, make the 500
error non-fatal, i.e. your Internet connection is probably fine.  But
what should it do if your network connection drops out in the middle
of a DX4WIN update?  You'll get the "non-fatal" 500 error for each
subsequent download.  I'll think about this, but will have to do it in
a way that doesn't break anything.
