My activation code doesn't work. I ....

I lost my original activation code. I posted here yesterday. I got a response on how to get a new activation code sent to me. The code was sent to me, but it is much bigger than the place for the activation code. It said my activation code is invalid. I have 5 days left before my avast program is over. Any help?

  1. Download avast! Free Antivirus: http://files.avast.com/iavs5x/avast_free_antivirus_setup.exe
  2. Follow instructions: http://www.avast.com/uninstall-utility (Run this tool for all prior installed avast! versions…!!)
  3. Reinstall avast! with the downloaded installer from point 1.
  4. Reboot.
