Wildthinks I tested "_listedownloadprogramme" as WebQuery name and it worked here. I dont know what problem you encountered but I created a new webquery named "_listedownloadprogramme", then added the $_listedownloadprogramme variable into my webtemplate and it listed the results.
as for second one: ($_listedownloadsprogramme/$_listedownloads) yes you may have a point. I noted it down and will check it in the new release if there will be a new release
