I have Adobe Acrobat 10 and have used it since 2011 but now it doesn't work
I have Adobe Acrobat 10 and have used it with a serial number activation only since I purchased the software Adobe Acrobat Pro since September 2011. Today I tried to create a PDF file from my Microsoft Word document and a pop up screen comes up asking me to sign in to Adobe and repurchase the software. What's going on here? Why do I need to purchase it again ... I paid for a serial number only activation back in 2011. Do I need to purchase the product again now?
