I renamed it instead of unpacking it and it's working as I write this (knock on wood). Can you say nooooooob!? Too funny. See what happens when we Windows types start meddling in tech we don't understand? This has been some fun learning though.
So if it just needs to be renamed, why doesn't the download just have the right name to begin with? I understand that there's probably a good reason - just trying to learn.
