Suddenly I can't access Mybooklive at all

I went away for about a week, and had my computer off during that time. Before I left, everything was working fine. I had tried some firmware updates, but they didn’t take. I think it’s because it was too full. Anyway, I come back, and now all of a sudden I can’t access it anymore. I had it mapped to a network drive and that doesn’t work. I can’t access the UI either, nor any of my shortcut folders or anything else. Plex I guess somehow remembers what was on there, because the libraries appear correctly, but nothing plays. I tried restarting everything, modem, router, mybooklive drive and computer, but that didn’t help. The mybooklive starts off with a blue light when I plug it back in, and then it goes green I think, but could maybe be a red or orange since I’m a bit red/green colorblind.

Any ideas? I’m not sure what the reset button does on the back of the mybooklive, but I’m thinking this is my only option at this point.

Anybody? Am I just screwed? Should I press the reset button? What does it do?

can not access my book?
