Hi kawaknaller,
It is not necessary to reinstall the game to access other languages.
You can temporarily change the language in the registry:
HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Vstep\ShipSimExtremes Language_Ingame
from NL to EN.
You can change it back again when you are finished.
If you are not comfortable with using regedit, the Registry editor, you can send a PM to me. I’ll send instructions.
Regards,
Marty
