I am sorry, I can not see that link you shared. It is a local link to a file on your computer, so only you can see it while you are on your computer.
I am not sure what is happening. Perhaps the wrong .pot file is being loaded? Regardless I think I can make this easy. This zip file contains the update files. There should be not need to update from sources as I have already done that. Zip: community-3-10-pt-BR
Does that file work?
Cheers!
