indeed the script work sonly if u have exactly the same aliases!
I mean es_verein , de_verein , en_verein
Now, if u delete en_verein and try to re-create it you'll have to clean up in mysql to avoid the system creating for u en_verein_frz or en_verein_erd because in mysql table en_verein still exists, even if u deleted it from backend.
So, the solution is to go to mysql and delete manually en_verein
For my multilanguage pages (almost always fr/nl/en) I create the structure names in english so it looks more "neutral".

Btw, to be exact (correct spanish) you should write "La asociación"
