I have SkyDrive applications installed on two machines -- a Windows 7 laptop and a Windows Surface Pro (8.0).  Historically, synchronization between the two has worked without issue, and I have not changed anything on my account.  I have confirmed that I can log into SkyDrive online.

On the laptop, as of today all of my files in the local SkyDrive folder have the "need to sync" icon (kind of a blue icon with circular arrows.)  On the Surface Pro tablet, none of the files have ANY SkyDrive icon (neither the green checkbox indicating the file is in sync, nor the blue "need to sync" icon.)

On the laptop, the SkyDrive icon has the green "doing something" indicator, and when I hover over it, it says "SkyDrive - signing in."

On the Surface Pro, there is no SkyDrive icon in the system tray at all.

On the laptop, I've created a test text file in the local directory, and confirmed that when I log into SkyDrive in the cloud, through IE10, the file does not appear.

On the Surface Pro, I've created another test text file (with a different name) in the local directory, and confirmed that when I log into SkyDrive in the cloud through the browser, or when I used the "tiled" app for SkyDrive on the tablet, the text file does not appear.

Can someone please help?
