When I go to register comodo it uses an e-mail that is not mine?
Hi kbltek3, welcome to the forums.
You shouldn’t need to register CFP any more, the previous method of email registration was dropped following user requests.
In ant event, could you describe the circumstances surrounding the other email address you received & could you please PM that email address to me (please do not post it here). Thanks.
Thank you for your kind reply 
I already noticed in the donwload section
that providing an email-account was “not required”.
This was not the case some time ago …
