Default Can't update gs4 t-mobile CM 11 to next version

So I got a prompt saying there is a system update for my phone, I accepted it.
It simply booted into recovery, started some process and then it said failed.

So then considering it is the installer version I plug it into the installer. This time the screen on my phone looks like I've installed the ROM for the first time. But this time it went to recovery and just sat there. And then on the installer on my computer after a minute it said it couldn't speak to my device.

Using CWM I hit reboot and it says Android apps are updating but after that my phone is exactly how it was before and when I go to settings it says I have an update available.

What does this mean, and how can I fix it? My phone runs the ROM fine but it's not updating. All solutions will be considered
