I did not forget, because nobody sent it to me. I recall seeing a .7z file, but when I said I couldn't work with it and asked for a .rar/.zip version, I'm afraid no one sent me anything. I am sorry to say that I can't see anything on the page you mentioned, either, because it's in Spanish, and I'm afraid I don't read in this language.
If you have an updated Spanish translation(including the updated Readme, as it's very hard to search for Spanish words in the dictionary), please, send it to me at kulyok, at
yandex.ru - in .zip or .rar format.
Folks(and it's a general "folks"), I am happy to include translations - and to update them afterwards - but please, e-mail them to me in workable format first. (I just received an update of Dungeon Crawl Italian translation, a simple archive in .rar - and it worked. It's all I need, really).
