CS6 serial key invalid message

>Adobe support couln't help me and redirected me here

That is SO WRONG... nobody in a public forum is going to be able to help with a serial number issue

My only idea is that you have used your allowed 2 activations and the error message is not correct

BE SURE TO ONLY ASK FOR ACTIVATION SUPPORT TO ADJUST YOUR ACTIVATION COUNT
You may need to PERSIST or TRY AGAIN to find a support agent with more experience
