Upgraded to Windows 8.1 now NinjaTrader doesn't work

[Kaotik]

Hello I upgraded from windows 8 to windows 8.1.

Now I get this error message:

"NinjaTrader is having problems connecting to its' license servers. Possible Problems are a ) Your firewall software is enabled and you have not authorized Ninjatrader to access the internet b) Your internet service provider is having service problems or both license servers are down. Please ensure that your firewall software is not blocking NinjaTrader and try again in a few minutes."


I turned off my firewall, that didn't work. I uninstalled ninjatrader and cleaned my registry and reinstalled ninjatrader and I am still getting the same message. Is Windows 8.1 not supported? Thanks in advance for your response.
