"Please make sure you installed everything correctly and no other mod has overwritten this file. Etc..."
I get this message when I open my map. I am using the STEP core install and followed the STEP instructions for the quality world map mod:

- repackage .7z archive, removing all top-level folders, except for "Map Standard Main Roads - HiRes"
- install re-packaged archive into MO
So I only have the "Map Standard Main Roads - HiRes" folder in a RAR file that I installed within MO.
Any suggestions? Thanks.
