Good Afternoon, Nanda.
I just purchased AA. I downloaded the software, then I opened it, for the first time, and I received a message that asked for the "code". I had the code copied when I saw it on the download page. After I pasted the code, I also got an answer to say that the code was incorrect.
I went to my email, and found a welcome message from either AA or Jon Ledger, i am not sure which, with also a code. I copied and went back to the software, and when I pasted the code again (this time from the email), it was successful.
