Depending on what launcher your son is using, the files will be in different places. I would just use google to find out where the launcher stores its files. Most launchers will have a button in the settings to open the file location. That should take your to a folder named either  or. Then go to the following location: /saves/ /LOTR/players/ There should only be one file in there and its name should be your son's UUID. You can find his UUID here. Let me know what your find there and we'll see what to do next.
