Ok now I think I got it. The problem seems to be that menu_1072_768.ini is not working properly - so I checked the package again. I found another careless mistake for JSGME users. Menu_1072_768.ini file is in a wrong place in the package. JSGME can't find it from where it is now, I think.
How to fix.
1. Unpack mod package.
2. Cut Menu_1072_768.ini
3. Move to data/menu
4. Paste.
I'll make another (yet again!) updated version of the mod to the downloads section in minute or two - which hopefully works as it should work
