Olá pati22,
na parte 4 e 11, seja em que horário for, mesmo depois de forçar o router a ganhar novo ip público:
"All free download slots are in use. You can download this file immediately by upgrading to FileFactory Premium. Otherwise, please feel free to try again shortly. Retry Download."
na parte 10, depois de esperar os segundos necessários e clicar no "download now" (sem a checkbox do download manager), abre outra tab do browser a dizer "Unfortunately the file you have requested cannot be downloaded at this time. Please contact us and let us know about this issue."
obrigado
