Problem syncing to device using WMP. Windows7

After I drag the tracks that I want to synch to my device, click on start synch" Cancelling Inspection of files on device" appears and tracks don’t transfer to device but yet it says that synching is 100% completed when it’s not.

Apparently there is a Win7 troubleshooter to help fix this…maybe:
