Cisco ASA 5505 Memory Upgrade

Hi Folks! So I was trying to update my Cisco ASA 5505 my buddy gave me from version 8.2 to 9.1. However upon reloading the device with the new 9.1 image file I got a warning on the console! I received the error of purchase Cisco item “ASA5505-MEM-512=”

Do a reload and verify the new version is the one being used.
