hello! has anyone ever had this problem? Normally the software works very well I even used it yesterday but today nothing works. I tried to download another version because I am in v5.0.0beta and even the other versions don't work either. It's the same message. on my other computer the software works very well but I don't know what to do... is there a way to contact the company directly?

    Hi @JYamada

    Thank you for your email inquiry as well.
    We apologize for any inconvenience this may cause.

    Could you please try the following procedure to see if it improves the situation?

    ・Uninstall the graphics board driver and reinstall it.
    ・Uninstall and then reinstall Cubism Editor.
    ・Check if the graphics settings on the Windows OS side are set to use a graphics board.

    Best regards.
