First thank you for your attention.
Here at our company ( in Brazil) we have a problem with the NODEXL. It was installed correctly but for some reason it does not accomplish more connection with the services (youtube, twitter, etc).
It displays the message REQUEST FAILED and presents the message proxy authentication required. We have a proxy configured here, but I wonder know what the service or port that it uses to perform the unlock in our firewall???
I using Windows XP and 7 32/64bits + Office 2010 Professional Plus
I waiting for your reply.
