installed a version of CAD on my laptop. Then, per the "Software License Agreement" section 3.1.2 (ii) w/ emphasis on (b). I went to install the same copy of CAD onto my main workstation. When attempting to activate the second installed copy using the activation code from the first install I received an error. I went back and selected "Register and Activate". It then immediately told me that it had been registered, bypassing the information entering screens. This time it gave me a second and totally different activation code. Is this something that could potentially cause a problem down the road? Shouldn't I have just one activation code per licensed version of AutoCAD? If so what should I do to resolve the problem? If my station dies and I need to load CAD onto a new station, shouldn't I just be able to enter the activation code that I recieved from registering the product the first time?
