Hi Dck_W,
What do you mean by files coming from the network? Are all your files affected by this? I suggest running the Initialization tool to help resolve this issue. Add the folders in the initial setup page of PlayMemories Home. All compatible files should show up on the page as thumbnails. If the issue is unresolved, uninstall the program and install the latest version of PlayMemories Home.
Please make sure you are logged in as an administrator before installing the software.
