I recently got the new MacBook Pro OS X 10.9 and when I started up my computer I transferred all of my information over to my new Mac from my old MacBook (2008 version).
I was happy that my Acrobat XI Pro transfered over, but it only transfered as a "trial" software and all previous records of purchasing my sofware in my account at Adobe are now gone. I thought I would be fine because the trial software frequently reminds me that it is a trial, and prompts me for my serial number. I have my serial number from my previous Acrobat saved and entered that number. When I do, this message pops up,
"This serial number is not valid for Acrobat XI Pro. You can either use a valid serial number for Acrobat XI Pro or use this serial number on the appropriate product."
Please help, my trial ends soon and I've run out of options. I can't lose this expensive software!
