Hi there.
Unzipping isn't the same as installing.
View that readme, and you'll see that you have to extract those 4 .cfg's and the readme into your SH3 Commander\Cfg folder...so you need to use the Browse-button, to find that location, and then unpack the 5 files there.
After that's done, you can close the zip-file.
(a small tip: to select multiple files, hold Ctrl while selecting)
