como habilitar um fluxo desativado?
This translates to "How do I enable a disabled stream" in English. I do not know what you mean by "stream" in there.
Most of the more active people here work in English, so if you want a faster answer, you could explain what a "stream" is for us. A screen shot maybe?
I am sorry that I cannot speak another language, and cannot help without asking for translations.
