Olá Srs, Boa Tarde!

Bom estou tentando guardar as minhas configurações no App.Config, no entanto consigo ler, mas salvar, nem dá erro, executa só que não atualiza o App.Config

Para Ler:
[txt-color=#0000f0]My.Settings.coringa
txt_usuario.Text = (My.Settings.userdb)
txt_senha.Text = (My.Settings.passworddb)[/txt-color]

Estrutura do App.config

<?xml version=[Ô]1.0[Ô] encoding=[Ô]utf-8[Ô]?>
<configuration>
<configSections>
<sectionGroup name=[Ô]applicationSettings[Ô] type=[Ô]System.Configuration.ApplicationSettingsGroup, System, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089[Ô] >
<section name=[Ô]Vendas_Control.My.MySettings[Ô] type=[Ô]System.Configuration.ClientSettingsSection, System, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089[Ô] requirePermission=[Ô]false[Ô] />
</sectionGroup>
</configSections>
<startup>
<supportedRuntime version=[Ô]v4.0[Ô] sku=[Ô].NETFramework,Version=v4.6.1[Ô] />
</startup>
<system.data>
<DbProviderFactories>
<remove invariant=[Ô]FirebirdSql.Data.FirebirdClient[Ô] />
<add name=[Ô]FirebirdClient Data Provider[Ô] invariant=[Ô]FirebirdSql.Data.FirebirdClient[Ô] description=[Ô].NET Framework Data Provider for Firebird[Ô] type=[Ô]FirebirdSql.Data.FirebirdClient.FirebirdClientFactory, FirebirdSql.Data.FirebirdClient[Ô] />
</DbProviderFactories>
</system.data>
<applicationSettings>
<Vendas_Control.My.MySettings>
<setting name=[Ô]userdb[Ô] serializeAs=[Ô]String[Ô]>
<value>1</value>
</setting>
<setting name=[Ô]passworddb[Ô] serializeAs=[Ô]String[Ô]>
<value>123</value>
</setting>
<setting name=[Ô]coringa[Ô] serializeAs=[Ô]String[Ô]>
<value>123456</value>
</setting>
</Vendas_Control.My.MySettings>
</applicationSettings>
</configuration>

Para Salvar:
[txt-color=#0000f0]My.Settings.userdb = usuariocriptografado --> AQUI DÁ ERRO DIZ QUE é SOMENTE LEITURA
My.Settings.Save()
My.Settings.Reload()[/txt-color]

Como resolver isso?

TUNUSAT, muito obrigado pela dica, mas, lendo já estou normalmente o problema é que não consigo SALVAR ou atualizar no App.config, já tentei inúmeros códigos da internet e nada, você teria algum exemplo que tenha como salvar os dados no app.config?
