Using windows 8. Was getting network error but I have followed the troubleshooting guide and now I am getting the error code in the thread title. Requesting some help, I just want to live in the nostalgia of old maple!
I would go into the control panel and uninstall the game, then delete the folder and reinstall the game. Also after you have reinstalled the game change the compatibility, by right clicking the client Properties > Compatibility > Run in compatibility setting > and apply Windows 98 / Windows ME.
If you didn't change compatibility setting, you might be getting parameter incorrect error. So you know that one can be fixed
