Update error while updating Samsung phone

Hi,
I have been updating my Samsung phone (Windows OS) with my PC but suddenly I got this update error message. What do you think should I do? I am afraid to tinker on my phone since I might corrupt stored photos, videos and music. Can someone guide me on how to remove the problem?
Thanks in advance.
