Hello!
I was just about to start a HaxeFlixel tutorial, this is my first time getting into Flixel stuff (coming from Flashpunk and a liittle bit of Haxepunk).  I got everything set up, got flixel and flixel-tools installed, all that--but when I went to build the template project, I got the error in the topic line.  I looked it up in the forum but there was only one topic about it, and it was pretty unhelpful.  I checked; I have flash 11.8 installed, so thats not the problem.  I'm stumped.  What should I try next?
