5th gen iPod shows in iTunes but won't sync

Hi,

I cannot sync the music from my PC with Windows 8 to my 5th gen. iPod.

The iPod shows up in iTunes but when I click sync it says "complete" but nothing has synced to my iPod.

I did I full factory restore on the iPod and have tried restarting the iPod, iTunes, and my computer.

My computer is authorized.

I also made sure to un-check the "manually manage" and "disk use" options.

Any suggestions?
