DarkRadiant does not see textures / crashes with "Failed to locate map format module" error

[Devil Master]

I have recently installed Dhewm3 (with the Doom 3 demo) and DarkRadiant. I know my way around GTK Radiant and Preditor, so I assumed DarkRadiant would be a walk in the park. However, I'm getting these two problems I never got with the other editors.

1) I have installed DarkRadiant from the package darkradiant-3.7.0-x64.portable.7z. I launched it, configured it to use the Doom 3 demo (Game Type: Doom 3 Demo), selected the folder where the Dhewm3.exe file is located, but it cannot find any textures.

2) If I try to make a test map (a square room with no textures, a player start) and save it, I get an error message that says: "Failed to locate map format module". Subsequently, nothing gets saved.

I have pasted the DarkRadiant log at https://pastebin.com/YAGv2u5h . You can see a screenshot showing the problems (error, no textures) at https://imgur.com/a/qVhx4dv. How do I solve these problems?

It's possible that the Demo game definition is out of date and needs some looking into (it might lack the "type" attribute in its <game> tag).

Have you tried to select the Doom 3 type instead of the demo?

I got rid of the demo and installed the .pk4 files from the retail version of Doom 3 (updated to the point release) into the "base" folder. The game works fine, and I'm not getting the error anymore, and now the (textureless) level gets saved, but DarkRadiant still doesn't see the textures.

I'd need to see the logs. Is the MediaBrowser populated with available textures?
