why do I have to keep changing my preferences, each time I log in?

It's keep changing to Portuguese

It's not clear, but I suppose you're talking about the forum language preference.

Even if you set & save your default language to English (for example), it goes back to pt?

EDIT: I tested it on forums and it happens here also.

I suggest that you create a thread at this board: Feedback on NI Discussion Forums

It's more appropriate for your problem, and the moderators you help you a lot.

Regards.
