Question
Desktop Acrobat Pro DC on Mac with Yosemite suddenly stops allowing editing and wants to be reauthorized.
I have had an installed desktop copy of Acrobat Pro DC working perfectly on my Mac for several months.
Suddenly today, it has locked all the features and insists that my copy is not authorized. It sends me through the authorization script, but when it asks for my serial number credential, it returns an error saying that the serial number is not correct.
Please advise.
