Half of those errors you posted are for the addon called Gatherer, not Carbonite.
For the Carbonite errors, I'm going to guess from other threads I've seen that the issue stems from the language. Carbonite has not been localized to Brazilian Portuguese.
In a nut shell, Carb is looking for specific names, like Elwynn Forest for instance, but it see's a strange unknown name so it throws errors.
There is work started by others
over here to localize Carb to Brazilian Portuguese though. I'm pretty sure it's just going to be a waiting game for them to complete their translations.
