It seems your English is pretty good so why not try the US or UK help sites for a chat session.
No problem with English. If US or UK chats can solve licensing issues in another country, I'll go there.
IIRC licensing is a global issue not restricted to regions. There is no Adobe Italian that is a completely separate entity from Adobe in the US or UK or France or anywhere else. Sure there are different versions of the website, languages, with local, regional, versions of all the software and support forums but it is still all Adobe.
I contacted the UK chat and the problem has been solved.
Maybe a hint about UK chat being ok should be placed on the IT chat page, so people capable to speak english can reach the solution in a quicker way.
