First of all thanks for the help.
I spent a pair of hours working on the project, following your pattern I could (I honestly do not know how) to get the three files needed to upload (.tar.gz, .changes and .dsc), but I can not try because extras assistant is offline.
For the moment I can say that I was not able to use the wizard to complete the upload .. If you will go wrong, go back to the old version.
I will try tomorrow, Wish me good luck
