On my Windows 8 desktop I keep getting error 0x80073cf9 when I try to install or update an app from the windows store.

In the installings apps pane it just says "This app wasn't installed -- view details" and when I select that it says "Something happened and this app couldn't be installed. Please try again. Error code: 0x80073cf9"

I am using the built-in windows firewall and antivirus. And my laptop is able to install updates when it is on the same network.

This is what winstore.log shows when I try to update the maps app:
