Hello!
To all that showed such good will to help me, I add a strange thing: as I had never more used eMule for all problems I was encountering, last Sunday, after the Rwin10 (I call Rwin because in Portuguese 'bad' is 'ruin', the same sound as Rwin and as I do not like this OS I use this subterfuge) I tried once again and, to my surprise, everything run smoothly. Even my ports were recognized. So, what to think I do not know.
Just to thanks very very much to all of you.
