I followed the guide, and finding that the torrent would take up too much time. I opted to install the launcher. It hits 100% then closes down, each time.
Whenever I re-open the launcher to see if I can play, I have to reinstall everything. (And it is a rather quick download).
I've included a screencap of the 'Epsilon' Folder on my C:/
Sorry if this is a bother, I'm just new and also not very computer technical at all lol
