Hi, Having had my previous machine condemned, I now have a new one and have installed my Mathcad 13 on it. During the installation I entered my Product Code but the on-line automatic activation no longer works despite an active internet connection! Emails just spawn an unhelpful automated reply and I have tried three different ones but they all trigger the same relpy. The link in the reply I can find no way past even with the legitimate credentials that let me join this forum. At the moment I have selected the Activate later option but this is for a 30 days evaluation. My Product Code is: Genuine but I won't post it here. How do I obtain the 20 character activation key that I need to activate my Mathcad 13 manually. Regards, Les
