LMS 7.9.0 cannot see music files on fresh install of OS6 on Netgear ReadyNAS Pro

I have a ReadyNAS Pro Business edition box that has been running LMS successfully on Netgear OS4.x for many years. Most recently I was running LMS 7.9.1 with no issues.

This week I installed OS6 successfully on the NAS (RNDP6000). After verifying the successful install, I restored all the music files that I had backed up before the factory default to do the OS 6 upgrade. No issues with restoring the files.

Then I followed the developer's direction (super-poussin) on how to install LMS on OS 6, which is to install 2 files in this order:
1) logitechmediaserver_7.9.0~1475786002_all.deb
2) lms_7.9.0_all.bin

Both files installed without error or issues, and the LMS web interface opened as expected. I used the Browse button in the web interface to select the Media Folders folder on the Basic settings page. I found the Music share, selected it, and found /data/Music in the Folder text box afterwards. Then the scanner began scanning the Music share, but it doesn't find any of the music. I know the files are there because I can connect my Windows desktop to the \\readynas\Music share and see the folders and files.

So my question is how can I get LMS to see the files in the Music share?

Any help understanding and fixing the problem is appreciated! BTW, I'm also new to Linux, so it could be something dumb I'm doing or not doing. Please point that out if so.

TIA,
David
