How to register Avast 5

Good Afternoon,

I installed the Avast 5, it seems it’s now registered, i can see the high-lighted word “REGISTERED” in the top of the screen when i open Avast, but each time i start the notebook, there’s a check-box saying that the license key was not introduced. Can you help in this?

I use Vista 32, and the Avast free version 5

Check your system date/time settings. Are they correct?
