Question
Acrobat XI Standard Suddenly Stopped Working
As the subject line says, Acrobat XI suddenly stopped working. So I uninstalled the product and reinstalled it (from disk). Message says that "serial number is valid by a qualifying product could not be found on this computer". Confusing, because I literally just reinstalled it. And it was working right up until yesterday. So I go to the "Customer Support Page" and a new message tells me that
The Adobe serial number you entered is invalid
It may be blocked due to misuse — or expired.
What does this mean? Who is blocking my serial number? How can a one-time-purchase software license expire? Is this all just a ruse to force me to buy a subscription?
