Skydrive has not synced in about a week.  I don't know why.  I'm not getting any messages that would explain it.  It is syncing if I go to skydrive.com and sign in but I can't edit the files in Micorsoft applications.  It is not synced when I enter Skydrive using the desktop icon from when I got the Microsoft apps.  Should I uninstall the Microsoft apps and re-install?
