Question WugFresh NRT Restore not working!

I tried to post this on a more appropriate location but I was told I was not allowed to post there because I'm a new user.
Regardless, I'm having a huge issue. I use NRT to backup my Nexus 4, but something has happened that resulted in a factory reset, and when I press Restore nandroid backup, nothing happens. I can click on it dozens of times if I want, and nothing happens. nothing I have done has caused it to actually work. What is going on?

my phone is totally on factory settings now and I'd really like my backup to work so it can be back to normal. otherwise, what is the point of backing up?

I am using Nexus 4, Android 4.3.
