If you tried to obtain a TU license for Rhino and you did not receive one. That could be right, because the spam filter of the TU Delft deleted those e-mails.
It is fixed now, but you have to enter your TU e-mail address again to receive the e-mail with the license information.
Somehow the mail server of McNeel has ended up in a blacklist. This means that e-mails from mcneel.com were considered as spam and automatically deleted by the spam filter. Settings have been changed to prevent this in the future.
