I recently downloaded The Free Comodo. Now it is asking me to enter code they emailed me to register my firewall. Problem is I did not receive any emails or codes. What do I do now?
In several other cases like this, the activatin email was found to be in the JUNK folder in either the email client software or on the ISPs email server junk folder (Hotmail, for one, does this). Check the junk or spam folders and see if its there.
Hope this helps,

(CLY)Hi,
I had the same problam until someone on this site told me to look in my spam mail and there was the email with the registration certificate number.
Good luck
