I'm back for help! looks like aMule has lots of problems in contacting the fonts that are not on the server you're connected to.
If I perform a "global" search, it finds 156 fonts for a file, but when I try to download it, aMule just sees 1 font... that bothers me. And sometimes I get errors like "Impossibile leggere dal descrittore del file X (error 5: imput/output error)" (its italian...).
