I forgot to add my suspicion that sumotorrent might have changed it's layout and therefore needed a change/update in the query script.
I can't remember having problems with Bit Che <> sumotorrent before, but it might be coincidence that I haven't chosen to download from it.
Because it's been only recent, that's why I suspect sumotorrent has changed something in it's web-page layout or query engine.
If required I can provide the good & not-good versions of the .torrent file for your comparison analysis.
