I have photoshop CS3 installed on my imac running Software OS X 10.8.3 (12D78) and after using it for the 30 days as i was a little lazy to activate it requested from me the activation key / serial number to countinue. when i entered the correct serial number it gave me an error saying the serial number is not Valid !!
the adobe has been used on my other macbook for the past 4 years without any probelm!! now it said it's not vaild.
i have conacted the customer care and after chatting with them for 1 hour they directed me to the fourm saying that it will be solved here.
That's nonsense. Nobody here can resolve serial number issues since nobody can look into the customer and registration databases. Use the chat again and request a more qualified operator.
Exactly what Mylenium said.
Make sure that you are contacting Adobe Customer Support, and not Adobe Technical Support - very important distinction here.
Thanks for your answer .
