Black Nav map problem

[smithcorp]

Hi all - I'm having a strange problem with some DW scenarios I downloaded from Sub Guru's site. They are a pack of Demo Scenario Mods by BrettDez that appear to be modded demo scenarios.

When I start them (DW 1.04) the Nav map is pitch black. I have tried to open them in the editor to see if the Nav map view was disabled, but they don't show in the list.

Here's what I see:



Any ideas what it could be and whether I can fix it? I'm pretty sure the Nav map should be showing.

Other scenarios work just fine.

thanks
