Hi, first off you have a warning message at the bottom that will be key - you cannot have a workgroup name that is no different to the netbios name:

The other is that you appear to be creating a share on a Windows folder from Zorin - I don't think you can do this - you need to set permissions firstly on the folder within Windows.
Also consider putting information you want to share in the 'public' user folder on Windows.
(C:\Users\public\shared ***).
Other things that can prevent you accessing Windows 8 files is the power options that are hidden - you need to turn the 'sleep' mode off in 8 (basically 8 goes into 'hibernate' mode when you shut down Windows 8 so it never really shuts down - GNU/Linux has always relied on Windows to shut down cleanly if you want to access files and folders on Windows from within GNU/Linux OS).
