Firstly, please make sure you are running the latest version of JOverseer.
Then try opening JOverseer using the joverseer.bat file file instead of the exe, found in: program files (x86)/Joverseer.
If that doesn’t work, create an empty text file, save it with the name:
DontUse3d.txt
Then move the file to the JO directory of your computer: program files (c86)/JOverseer. (You might need to enable admin privileges on your computer to do this.)
Then run joverseer.bat
