As this service is free i like to ask.. Long story short...How can i deactivate my cs3 design premium on my mac so i can successfully reinstall and input a new serial number. when i go to the help menu in Photoshop there is no option to deactivate listed on my software. As i have learnt you need to deactivate before you reinstall with a new serial number? I have also tried deleting files from cs3 associated adobe files before uninstalling in the hope after reinstalling that it will ask me to type in my serial number.. i hope i made sense.. Can you help and thanks for reading..
