Kodi stuck at preparing

UGH!

So I set up Kodi 16.1 on my new Nvidia Shield TV and got it to connect to my home network. My network consist of a Windows 7 PC/ Verizon fiber router/CAT6 ethernet cable. I added Movie and TV sources and Kodi scraped them without a problem. I also added a couple of add ons. Everything was going swimmingly until for whatever reason when I last opened Kodi the usual library update notice in the upper right corner got stuck at “preparing”. It never got unstuck (well, at least for ten-ish minutes) so I rebooted and its still doing it.

The funny thing is that I returned another Android box because of this behavior. I thought it was the fault of the other box, but clearly this is about Kodi and/or Windows and/or my network.

When it does this I cant do much of anything with the program. It allows me to scroll to the power button which then gives me an exite menu but pressing that does nothing, I cant exit Kodi and I cant use Kodi. Kind of a bummer

Anybody else run into this?
