You need to download all 8 files in the list in my first reply. But you don't click on any of the .bin files. You don't have to open them or run them or do anything other than save them all in the same folder with the GXW3.exe file.
When you have all 8 files saved to the same folder, double-click the GXW3.exe file. That's the only file you need to click on.
