I just purchased ADT 2006 and activated it, then applied SP1 due to some issues that non-sp1 had with a lisp program that our office uses. After the SP1 update it required that I re-activate the product and I tried the same code to no avail. I told it to re-activate and it said that the key was already activated and not available to activate. It is a legit key I purchased form a very large retailer in CA, and I am the only one with access to the key or CDs so I know it wasn't used elsewhere or stolen. Has anyone else had these issues? And why is Autodesk requiring this privacy and security discarding BS anyways? Greedy-assed bastards.
