No, Pligs, I don't think the file I mentioned is on your site. However, something strange is happening, probably due to my lack of knowledge of Polish. When I first clicked on your link, I got a list of (Conax?) files which, as you said, contained no download instructions. However, when I clicked for a second time, I got a list of downloads, many of which are on other sites such as Phill's and Dragon. I copied the URL from this page. It's: http://sat-digital-tv.admin.net.pl/upload/index.php?lang=english&skin=0 Downloading from here appears straightforward IF you can find the Conax file.
Stupidly, I didn't note the URL of the site from which I downloaded my Conax files. I think it was Phill's, but am not confident that it was. Anyway, I've PM'd them to you. Let me know how you get on.
