Add the parameter values in the same order as the parameter names appear in the UPDATE statement.

cmd.Parameters.AddWithValue("@firstName", firstName);
cmd.Parameters.AddWithValue("@lastName", lastName);
cmd.Parameters.AddWithValue("@Gender", Gender);
cmd.Parameters.AddWithValue("@Address", sAddress);
cmd.Parameters.AddWithValue("@Telephone", sTelephone);
cmd.Parameters.AddWithValue("@Course", sCourse);
cmd.Parameters.AddWithValue("@Email", sEmail);
cmd.Parameters.AddWithValue("@UserName", User.Identity.Name);

OleDb with Access does not pay attention to the parameter names, only their order.

add the parameters according to the order in the query

  string sqlQuerry = "UPDATE aspnet_Users SET firstName=@firstName, lastName=@lastName,  Gender=@Gender, Address=@Address, Telephone=@Telephone, Course=@Course, Email=@email WHERE UserName=@UserName";

    OleDbCommand cmd = new OleDbCommand(sqlQuerry, oleDBConn);
    cmd.CommandType = CommandType.Text;
    cmd.Parameters.AddWithValue("@firstName", firstName);
    cmd.Parameters.AddWithValue("@lastName", lastName);
    cmd.Parameters.AddWithValue("@Gender", Gender);
    cmd.Parameters.AddWithValue("@Address", sAddress);
    cmd.Parameters.AddWithValue("@Telephone", sTelephone);
    cmd.Parameters.AddWithValue("@Course", sCourse);
    cmd.Parameters.AddWithValue("@Email", sEmail);
    cmd.Parameters.AddWithValue("@UserName", User.Identity.Name);
