Does your PC appear under „Show Network Devices“ on the Filesystem/Mount page? If Windows 10 is now running on your PC, you may also have to reactivate Samba 1.0 there. Search for „Turn Windows Features on or off“ on your PC and activate „SMB 1.0/CIFS File Sharing Support“ there. Apart from that I can only recommend that you delete the file share and set it up again.
