Hi to everybody,
and thanks for your further help.
I have no internet at home, so I decided to download the FreeDB database (wow, 700MB!) to have an offline database.
I follow all the steps, and Nero actually starts creatind the database from the FreeDB unzipped folders, but just at the end of the process, at 95% more or less, it fails! Son of a b.---- I did it several times, and I am pretty frustrated, as each time it is several hours wainting, to see the saem sad ending...
