Trouble Making Backup Copy of Weardale & Teasdale

I'm trying to make a backup copy of Weardale & Teasdale. Normally, I make the copy using Sync Toy.
The copy is stored on an SSD, which has always been offline, at least when playing TS. When I try to load the copy of W & T, I get a consist builder message, and there's no scenery.
This is the protocol I've always followed to make a backup copy. Did something change with TS 2017?
Thanks,
Rob
