Skydrive sync engine stopped working in Windows 8.1

My skydrive has been syncing information between my 2 windows 8.1 computer.  My desktop was uploading 2400 files and downloading 2.  I went into the skydrive folder and deleted files that where duplicates.  I got a message saying that the skydrive sync engine has stopped.  Stop skydrive and find a solution or just plain stop skydrive.  I tried both and closed skydrive and restarted it every time.  I got the same message about 4 or 5 times.  I no longer get the message but all of those files are showing pending.  Is there a way to fix the sync engine or do I have to restore or refresh the computer which will take a day or 2.  Please help.
