I can't get a free license

I have downloaded eM Client and now have a pop up message saying that the trial version has expired, I need to obtain a free license to continue using it. So I enter all my details and it fails because there is only 1 license per email address? I don’t have a license and cannot access my email until I obtain one, but it won’t let me? What am I supposed to do?

Give me your email address and I’ll send you your activateion key.
