Registration Question

I was advised that my trial period was ending, and so I re-registered. I received my key in an e-mail.
However, the program keeps telling me my trial period will expire and to re-register!!!

How do I stop it from telling me that when I have already done it?

Thanks

Well, did you enter the new key into avast!? (e.g. from the About box / License key)

Also make sure your computer’s time & date are correct.
