Invalid License Key

[bobby88]

Hi.
    I am a registered user of avast. I formatted my computer recently. I have installed Avast Home Edition v 4.8 but when I try to register using my License number, I get a message 'Invalid license number'.
 
    Please help me out.
    Thanks in advance.

Regards,
Rohith

  I already have the registration key but when I enter the key, I get this invalid license key message.

Did you follow David's tutorial to insert the key?
Are your system time and date correct (double check )
