can't connect to external server to validate license. HELP!

License problems
1

I have got a free license, but the computer can’t connect to an external server to activate the license

Hi, are you using any security software on your computer that may have disabled the applications ability to connect to the server? Make sure your computer can access http://licensing.emclient.com/ or Port 80 that is required to connect to the server.

Thank you,
Paul
