Acrobat X Pro became trial version after 4 years. How is this possible?
I had Acrobat X Pro installed on my ultrabook in 2012. There was no problem until today, when a prompt came up and said this was a trial version. This leaves me with 2 problems:
1. I have no clue where to find the serial number to add to this trial so it can move forward and I can work.
2. If I want to upgrade, I need a serial number from the old version. Where can I find this information?
