The place here-module version 1.2.1 didn’t quite work for some people and while I suspected it might be some simple problem I had no idea what actually was going on. It turned out, as it is often the case, that I was being stupid.
Between the previous and current version I had changed the sql query in the module to avoid a problem with date calculations that was not originally caused by my code (so if with future versions you get an error message that involves the words “JFactory::getDate()” please note that I won’t be able to help you). As a result the query failed (unless your server happened to be somewhere in my timezone).
I’m working on some items from the feature requests, so I haven’t released a new version yet, but be assured that there will be a patched version by the end of the week.
