When getting PID(0) before raising a support ticket there are a couple of things you can try:
- Check your config files - If you have made changes to the games config files rule out this as an issue by reverting back to the default config files.
- Check your command line - Make sure there are no mistakes in your custom command line.
- If the server is a Minecraft server ensure you have the relevant JAR file
- Re-install the service (ensure to back up any save files)
