        playeremail, livello, adminl, soldi, uccisioni, morti, idgiocatore);

to:

Code:

mysql_format(handle, query, sizeof(query),
        "UPDATE users SET email = '%s', level = '%d', admin = '%d', money = '%d', kills = '%d', deaths = '%d' WHERE id = '%d'",
        playeremail, livello, adminl, soldi, uccisioni, morti, idgiocatore);

And make sure that "email" is defined as VARCHAR with LENGTH 64 in MySQL Database.
