Fenix 3 won't sync

I was syncing my Fenix 3 this morning and it was taking forever. I assumed that something had frozen up. The bar was stuck at about 75%. So I did something I probably shouldn't have. I disconnected the watch from my computer. When I tried it again I got a message saying there were updates so I clicked yes but the updates failed. This morning's bike ride successfully uploaded but now every time I connect the watch to my PC it fails to sync. I don't get the gradually growing bar but rather just a short bar repeatedly swiping from left to right. I turned the watch completely off and let it sit for a while and tried it again but got the same results. I also remembered that when I started my bike app this morning before the ride it prompted me about an update but I said "no" so I could start riding right away. Now I'm thinking the initial attempt to sync that took so long was probably trying to do the update. Any suggestions?
