The EUP configuration file you downloaded likely does not match the version of EUP you have installed. For example, if you're using a configuration file built for EUP version 9.3, it would typically state "9.3." However, users may accidentally download a configuration file for a paid version like 9.6 or higher, even though they have the version labeled 9.3 in their game folder.
If the configuration file and EUP version do not match, try reinstalling EUP in the correct order - first Law and Order, then Serve and Rescue. After reinstalling, replace all the files in your game folder. This should help resolve the issue.
