My last laptop burst into flames, and therefore I cannot "deactivate" that license. I installed Adobe on my new computer, but it just gives me the message that I have to deactivate another license. The computer that burnt up was the only license I ever activated. I still have the original disks, but I cannot use the program that I bought and paid for. Certainly there must be some way to notify Adobe that the other computer can never run the program again, and get access to my program. I cannot be the only person who ever had a computer stop working without first being able to deactivate a license.
