Также пробовали способ из http://www.gotdotnet.ru/forums/2/79403/377856/#post377856 , но выдает точно такая же ошибка . В трейсе пишет «Cannot find the certificate in either the LocalMachine store or the CurrentUser store» возможно из- за того, что после добавления сертификата он не появляется Tools menu -> Internet Options -> Content tab -> Certificates utton -> Trusted Root Certification Authorities .
