I got a Lightroom license number in 2013 when I bought a Leica camera. I registered it under my Adobe Creative Cloud account and now the program is de-activated and claims that I should buy a license, not recognizing the one I already have. ¿Is tehre anything I can do about this?
The license you received from Leica is for a standalone perpetual licensed version of Lightroom, and cannot be used with the creative cloud. The creative cloud requires that you have subscribed to at least the photography plan which costs $9.99/month and includes the latest version of Lightroom as well as the latest version of Photoshop. It is not licensed with a serial number. If you want to use the Lightroom that you have, please indicate what version it is and what operating system you are using. Then we can provide you with a link where you can download the standalone version.
