Hello,
Registrered, yesterday.
Have not received new registration key.
Is the robot on vacation ?
Thanks.
Listed below are several reason why you may not receive your license key:
Filling in an incorrect E-mail address - the robot will send the message to this wrong mailbox and you won’t receive it!
Your mailbox is full - the registration message can’t be stored in your mailbox and you won’t receive it!
You or your Internet provider use a so called AntiSpam program and it blocks the registration mail as a spam.
Please ensure that emails from Avast’s addresses are authorized to enter your mailbox.

Not blocked.
A solution would be helpful.
How do I check to see if I entered my email address incorrectly ?
Should I register again ?
Should I use same info if I reg. again ?
If you are not sure, just register again and make sure you check your spelling & typos. 
In the meantime you can use the Demo Key which will give you 60 days unrestricted use. Plenty of time to resolve the receipt of a registration key.
If you have a second email account then you could try that one and see if that gets through.
If you or your ISP uses a Spam filter ensure that email from avast.com is white listed.
You can’t check this ‘in the past’ but if you register again, check before submiting the data to Alwil.
No trouble.
