    Microsoft SQL Server Express authentication error


    I have a C# project, which is a Windows Form application. I use Microsoft SQL Server Express 2022 for a database. When starting the application, gets errors, "can not find user A.M in database" and "User is not authorized".Can anyone help me with fixing these errors?

    :)

    SQL Server 2014 Express edition

    I install Sql Server 2014 express edition successfully on a notebook running windows10 2 days ago and manage to log into the server using SQL server 2014 Management Studio with windows authentication. But today, I'm unable to log on using the same login settings citing
    some instances or network problem.

    Appreciate it if anyone can enlighten me on how to solve this issue.

    Thank you in anticipation.
