Well, I tried to contact Adobe's support and realized that the software that I am a victim of software piracy. I wouldn't be surprised if you're all in the same boat.

Just like many of you said, everything appeared legit and sealed, and it even "let" me register the product online. That must have all been a front, because my "registered" software was not in my Adobe account, even a week after I "registered" it. When I tried to register again online, they told me that the serial number is invalid.

Sorry to rain on your parade.
