Folder Contents Invisible

Hi there, I have a Samsung PS59D8000 and am running Serviio 0.6.1 and have been sharing files across my wireless N network with no issues for some time. I am running Window 7 Ultimate 64 bit and do not have Homegroup shared libraries turned on and have uninstalled WMP.
None of the folders that are working and shared via Serviio are shared in Windows - they don't need to be.
I have multiple folders on several drives on my PC shared and they all work fine, however when I add a new shared folder via Serviio, I can see the folder on my TV, but the contents are not visible. The new folders are being created in the root directly of the drive, just like the other folders that work.
The new folders are on the same drives as other shared and working folders and the Windows share settings are the same (ie not turned on).
What am I doing wrong?
