Skydrive cannot synchronize with new files after windows update

I use Skydrive to manage all my documents and I have updated my operating system to Windows 8.1 and the installation went fine but now I can't properly synchronize with Skydrive I can only access to the files which were already there before the update and doesn't synchronize with new files. I get this error when I try to synchronize : "Error: We can't connect to your SkyDrive because the path of a file or folder is too long".
