Can an Acrobat serial number get highjacked by opening a PDF from another person?
I received a PDF from an unknown person that I had to open to complete an assignment. But Acrobat began acting very strangely when I opened it. I've had it 3 years and it's never behaved this way before. Once it was open, a minute or so later, an Adobe pop up requesting my serial number came up. I closed it. Then it did it again, I closed the document and the program. I then tried to go back into Acrobat and the program itself wouldn't open only the dialog box to input my serial number. I then had to go and search for my serial number to put in before I could open the program again.
Has this ever happened to anyone else? Mine has never done that before in three years. Seems quite odd to me that it just demanded my serial number before I could use it. Keep in mind I use it almost daily, if not daily with my work.
Just very odd. Thanks for your assistance in advance!
