NT7+Win8+zen-fire connection problem

[fmvin]

Hi all,
I experienced a common problem on forum as I can see.
I have zen-fire demo account provided by Mirus. I successfully connect NT7 (latest build) to zen on my 2 (two) Win7 machines. But on my main machine with Win8 installed I constantly get the error "logon failed. Please check your internet connections..." No need to say that connections settings are the same on all my machines.
I followed by all instructions I’d found on the forum: synced time, double checked user name and password, erased data cash, tried to launch 32 and 64 "NinjaTrader.exe" and so on. Also I several times reinstalled NT7 with the same result.
Please provide me solution. It will be unpleasant way out of this situation to downgrade to Win7.
Thank you in advance.
