Draftsight activation doesn't send email

Hi!

I've reinstalled some computer on Windows 7 x64 (to have 8gb of ram), and there is a computer, which I try to activate Draftsight, and it doesn't seems to work. I add my email address, etc... then click activate. It's says it has been sent, but it does 2 sdays, nothing in spam, no email.

How can I solve this? Any idea?

Thanks
