Strange behavior. Minimserver on Win10 PC

[glainc]

Set up a Minimserver on Win10 PC for use with Linn DS at shop.
Worked as expected. No glitches.

Shut down PC; bring it and DS home.
Everything looks great--until trying to play something.
-The Library appears showing all albums.
-The Main Room appears.
-Settings are as expected.
-Network for PC and DS are the same.
But.
Load an album, any album, any track, multiple tracks into Playlist window.
Press PLAY, and the DS starts at Track 1 and steps through, one by one, not getting them. And no sound of course.
This happens with any album or track chosen so far. Even ones we played here.

Rescan via Minimwatch. Which quit/relaunched Minimserver.
Still no go.
Uninstall Minimserver and Minimwatch. Download new. Reinstall. No go.

Funny that the new installation had the contentDir path pre-filled as if some info is being stored somewhere on the PC. First time, had to enter it manually.
Could it me storing track location data from the successful installation at the outset?

Anyone ever experience this?

THanks,
Tom
