I suspect either the site's owner (Simon Becker) or his service provider has changed access permissions on some service the converter needs to do its job. I've been using this converter for many years, and there have been a couple of occasions in the past when it's been broken (not in the same way as this time) and stayed that way for long periods.   I therefore suspect that it's inadvertent rather than deliberate that the converter has now become unavailable. I emailed Mr Becker about three weeks ago to alert him to the problem, but the email bounced because his inbox was full.

The previous time this happened, I resorted to Colin Hume's online converter, which is also very good, and am now doing so again
