I received this from AMP futures, posting it here for a heads up. Nothing received from Ninja Trader about this at all.

From AMP Trading, (Concerning Xen Fire)
"
If you have been using NT7 live, please make plans to use NT 6.5 on Monday.
NinjaTrader 7 Beta 18 is temporarily disabled from being able to connect to the Zen-Fire network to ensure that the network's integrity is not compromised. The cause of the disconnections last week are still unknown however, all technical teams involved are investigating.

It is not expect that there will be a resolution by open of US markets on Monday
If you have been using NT7 live, please make plans to use NT 6.5 on Monday
All versions of NT7 (previous Beta’s) use the same logic for connection handling so these versions are also susceptible to this connection issue and thus we will not make available prior versions"

Update from NT - Ray itself :

Tip UPDATE: As of earlier today, all NT7 versions are able to connect to the Zen-Fire network. Thanks for your patience and understanding. NinjaTrader 7 - Zen-Fire Connection Issue - NinjaTrader Support Forum -

does this mean zen + NT7 is working again + the probvlem is found + fixed ?


BTW- Thanks to webart for posting this here !

Ok thanks Max, I havn't been on the NT forums lately.

I havn't received an update from AMP, but if I do I'll post that.

Cheers

well - i dont know what this update -post exactly means - problem fixed or not ... its no clear statement for me yet.

also some folks still post disconnection-issues ..... so we wait + see what NinjaTrader or others will post here !

I am still on beta 17 and is working ok for charts. I use a different front end.
