I can't pass 'ETSI PDA Validation'. After registration a letter came saying: "In order to validate your account please reply to this message a blank email" The same e-mail comes every time I try to download a new standard. I've tried replying with various kinds of blank e-mails: blank body, with "Re:" and without, deleting original text and not with no luck.
Please help me, what have you answered to get access? Maybe I just have to wait some time?
