Well, I got the app running, so thanks :D
HOWEVER, with me being me, of course something weird happens. In this case, I put an LXF file in the "input file" section, and it automatically put it in the output too (that's supposed to happen, right?), and then I clicked "render." Instead of a rendering, however, I got a popup that said it couldn't locate the LDD database file and that I had to manually select a "db.lif" file. What is that, and how do I finally get this thing to render on my troubled Mac? :P
Thanks in advance
