installing NT on second machine

[Bypass98]

I have a permanent license and I want to install NT on my computer at home to trade at night. I downloaded NT and put my licence code in and it says that code cannot be varified, what is going on? I copied my license code from my computer at my office, emailed it to myself and then copied it from the email and pasted into NT newly downloaded to my computer at home. I got a message that said unable to verify license and when I help ->lincense key to enter my license it said "Ninja Servers could not be reached enter back door code here" I pasted by license code here and it said "back door code you entered is invalid" Can I please get some help?

Hello Bypass98,

Thank you for your note.

The error indicates that your installation of NinjaTrader cannot connect to its license server to verify the license you have entered. Please check for software such as firewalls, spyware and anti-virus software that could be blocking NinjaTrader. In some cases the modem/router has built-in software that prevents the connection to be established.

NinjaTrader itself connects to standard web address via HTTP protocol through whatever port is defined for internet browsing on the target PC (Port 80 by default) to connect to its license server.

Please let me know if this does not resolve the issue.

Thank you,
