Using a Mac and the Safari browser. Been down this path last time, tried downloading from a PC etc with no luck.
As for the .bin, what actually got downloaded for me was a folder named bin. It holds several different files. Maybe that is the problem... I'll download it again an see what I get from my PC at work.
