I’m going to assume you mean the domain string "wwwaggmaalcom upd" and that you want a methodical examination (e.g., what that string likely represents, safety/legitimacy, how to investigate it, and recommended next steps). If you meant something else, tell me specifically.
Your Activation Key is invalid
There are a couple reasons why this might have happened:
1) you don’t have an activation key and entered a fake one
2) you entered the wrong code
3.) You didn't sign up properly
Please double-check that you have downloaded your activation key according to the instructions in the tutorial video.
