I have a HP desktop using Windows 7 and Asus laptop using Windows 8, both on the same Microsoft account.  They were working just fine until a few weeks ago when I was primarily using the laptop.  When I returned to the desktop the changed files only showed the old version. 

Other than possibly adding a new folder, I have not done anything different.  I routinely save files that I expect to use on both computers to the SkyDrive.

I did not install the SkyDrive, it had been on my desktop for sometime.  When I purchased the Asus recently with Windows 8, I now had 2 computers and found it tremendously helpful to be able to work on files on both computes.  This worked fine until several weeks ago.  I use Outlook on both computers.

I am not sure which version is on either computer.
