First, thank you very much for your time!
But, I login as "administrator" and I have all permissions activated. So, I've access to all modules, including the module that I've created ("Manual").
I know this because I edited the user "administrator" in System -> CP Users -> Edit users. In fact, you can check this in IMAGE1 and IMAGE2, because in both images appear all modules activated in top menu, including the module that I've created ("Manual").
