I forgot to mention the qt.conf file. Delete it from the Programs and from the Launcher folders.
I updated the original post with this information.
Reinstalled Mint? Not due to SoH I hope. No files that belong to SoH reside anywhere outside the 'Shores of Hazeron' folder. We do not install any libraries or anything else onto your computer in other places. One exception is on Windows, where the Launcher lives in its own folder in the Program Files folder. The other exception is on Linux where the settings file resides in the .config folder of your home folder but that file is not binary and it does not indicate the location of any libraries; it is just settings.
