My AutoCAD LT was running fine for two weeks - then it said "License Expired". I cannot click "Activate" only "Register Product". When I click "Register Product" and enter the activation code that's on my box, it says..."activation code invalid"
Help me!!!! I can't get anywhere with people from Autodesk. I'm losing work too ....
An activation code will only be valid once / when it matches up with the request code used to create it. Can you please send me a Private Message (click on my philip.s profile name and then "Send this user a private message") with your serial number and request code, or contact our License Assistance team for additional assistance.
