Trouble getting second license

I’m trying to get a second free license for my laptop. I have a second email address, but when I try to use it to register it says that the email address has already been used. So I tried to use the tool to recover a lost key and it tells me “No such email found”. Confusing.

Hello,
we are sorry for temporary failure of our licensing server. You should be able to register properly now. But be aware that according to our internal laws you shouldn’t be registered twice as one person.
