How to download Adobe Acrobat X Pro in Portuguese?

I have a Adobe Acrobat X Pro (for the Portuguese version) license but, after formatting the computer, I can't find how the install this app (it seems Adobe stopped making old software available to download) and I just can't figure how to contact them to request them to send me the .exe file via email.

I've found this and this thread about that subject but the problem is my license is for the version in Portuguese (and some other languages) - I remember that when I used to download the file from Adobe I had to choose between 3 or more versions (one was in English, other was in Portuguese, and the others I just don't remember). Also, to be honest, I don't feel quite comfortable downloading this from other places than Adobe (but if it comes from a really trustworthy site and is exactly the same file that I would get from Adobe then I think that's ok).

Do you know how can I manage that?

Thanks!
