Oh my! Mac and windows downloads had the same name at some point, and the former over had overwritten the latter. It's fixed now. Please try again, and apologies for the issue!
Thanks for fixing it! Issues are part of the jam process, I'm learning. I certainly had a few to overcome myself. I'll definitely give yours another try.
If you have the chance to give mine a look, that would obviously also be awesome. if you haven't already :)
