mount - Error mounting NTFS partition after hybrid shutdown with Windows 8

I've got this error and I can't access my files located in a different partition when I'm using Ubuntu, but when I'm using Windows 8 my files are accessible. I'm using Ubuntu as my main OS. I tried shutting down Windows 8 properly but still nothing happened. Is there any way where this can be fixed?

Error mounting /dev/sda4 at /media/kris/BackUp Files:
Command-line `mount -t "ntfs" -o "uhelper=udisks2,nodev,nosuid,uid=1000,gid=1000,dmask=0077,fmask=0177" "/dev/sda4" "/media/kris/BackUp Files"' exited with non-zero exit status 14:
The disk contains an unclean file system (0, 0).
Metadata kept in Windows cache, refused to mount.
Failed to mount '/dev/sda4': Operation not permitted
The NTFS partition is in an unsafe state. Please resume and shutdown
Windows fully (no hibernation or fast restarting), or mount the volume
read-only with the 'ro' mount option.
