Adobe Acrobat X Pro quits and asks for serial number
I recently had to re-install a previous version of Acrobat (X pro) due to DC bugs and incompatibilities. Now every day, when i first boot the application it quits and asks for a serial number, which i have, I enter the number, the program works for the rest of the day, then same thing happens the next day. I am running creative suite CC 2015 as well, all on Mac OS X 10.10.5
Any idea how i can get Acrobat to not quit and ask for number every day?
