I'm using the latest Photoshop CC release (2014.2 at this point) and whenever I boot it with Quixel it won't let me drag & drop any files into PS.
I tend to open files this way most of the time, so it'd be good to know if there's a way to get this working or even if this behavior is intended for some reason.
I recall that there have been some problems with Quixel due to Photoshop's language being set to something other than English. So it might be useful to know that this is the case for my Photoshop.
Sorry if this has been answered before as it seems like a very basic issue to me. Nevertheless couldn't find anything on the topic.
