What could be the cause of 'Could not find installable ISAM' error in my code?

I can't figure out why I am getting an error here saying: Could not find installable ISAM. I am trying to add data to Access file which seems to have a problem.

I'm not sure why this wouldn't work since I am using almoust exacting code when deleting each entry.

Is there any obvious errors here?

        // Creating a query for each type of data.
        string sqlPC = @"INSERT INTO PersonalData([Type], [UserName], [Password]) 
                         VALUES(@Type, @UserName, @Password)";
        string sqlWS = @"INSERT INTO PersonalData([Type], [URL], [UserName], [Password]) 
                         VALUES(@Type, @URL, @UserName, @Password)";
        string sqlSC = @"INSERT INTO PersonalData([Type], [SoftwareName], [SerialCode]) 
                         VALUES(@Type, @SoftwareName, @SerialCode)";

    HashPhrase hashPhrase = new HashPhrase();
    Security security = new Security();

    private void InsertData(string sql)
    {
        string hashShortPass = hashPhrase.ShortHash(pass);

        string connectionString = 
            @"Provider=Microsoft.ACE.OLEDB.12.0; Data Source={0};
              Persist Security Info=False; Jet OLEDB: Database Password={1};";

        using (OleDbConnection connection = new OleDbConnection())
        {
            connection.ConnectionString = 
                string.Format(connectionString, filePath, hashShortPass);

            using (OleDbCommand command = new OleDbCommand(sql, connection))
            {
                OleDbParameter prmType = new OleDbParameter
                    ("@Type", security.EncryptAES(cmbType.Text, pass, user));

                command.Parameters.Add(prmType);

                if (cmbType.SelectedIndex == 0)
                {
                    OleDbParameter prmUserName = new OleDbParameter

                            (txtUserName.Text.Trim(), pass, user));
                    OleDbParameter prmPassword = new OleDbParameter
                        ("@Password", security.EncryptAES
                            (txtPassword.Text, pass, user));

                    command.Parameters.Add(prmUserName);
                    command.Parameters.Add(prmPassword);
                }

                }
                catch (Exception ex)
                {
                    MessageBox.Show("Error: " + ex.Message);
                }
            }
        }
    }

In my case, i Fixed so:

I change: 

string conexion = @"Provider=Microsoft.Jet.OLEDB.4.0;Data Source=C:\temp\Fa.mdb;Database Password=xxx;";

to:

string conexion = @"Provider=Microsoft.ACE.OLEDB.12.0; Data Source=C:\temp\Fa.mdb;Persist Security Info=False; Jet OLEDB:Database Password='xxx';";

I have changed: 

string connectionString = 
            @"Provider=Microsoft.ACE.OLEDB.12.0; Data Source={0};
              Persist Security Info=False; Jet OLEDB: Database Password={1};";

To:

string connectionString = 
            @"Provider=Microsoft.ACE.OLEDB.12.0; Data Source={0};
              Persist Security Info=False; Jet OLEDB:Database Password={1};";

And it works, I have had 1 unneeded space...

For the insert part you have a field named Password which is a keyword in MS Access. Your insert statement should include [Password] instead of Password.
