Problem compiling help RH2015
I'm having problems compiling help into Microsoft HTML, and Reponsive HTML5, the two formats I use. As an experiment I tried Multiscreen Help, which annoyingly - since I don't use it - actually works, but at least I guess it tells me that nothing is fundamentally wrong.
I can't think of anything I've done to break it, I haven't done anything on it for a few days since I last compiled.


I have no doubt I'm going to need to supply more detail here but where do I start?
