B11 - NT8 Crash when changing period for VIX

[music_p13]

When I tried changing VX 06-16 from Daily to Weekly chart using demo account for NT Continuum - got following in the log:
Failed to resolve instrument for market data: VXK6 is not enabled for real-time quotes and trading.
Failed to resolve instrument for market data: VXM6 is not enabled for real-time quotes and trading.

And following exception messagebox (which if click "Abort" - Crashed NinjaTrader).

Hello,

Thank you for your post.

Currently VX is only available for live accounts and is not included with NinjaTrader Continuum demo accounts.

So I may look into the error further please go to Help->Email Support and be sure to include Attn: Chris Jameson in the Subject line, a link to this thread in the body and a check in the box for "Log and trace files".

NT8 - B11 - connected to live data feed Kinetick Realtime.

Same error appearing frequently

- when switching instruments (for example from ES 09-16 to ZW 09-16)
- when changing the chart period (for example from 60 min to 1000 Ticks)
