I've moved your post to its own topic because the original topic you posted under was regarding NinjaTrader 7 which is fundamentally different than NinjaTrader 8.

What does 'complete reinstall' mean exactly? Walk me through, in detail, what steps you took.

Can you elaborate further about what 'gone' means, specifically? Where did you find these instruments/expiries before? What exactly are you doing to search for them now?

Does this persist if you reset your instruments? Follow these steps:

• First, disconnect from any data providers by navigating to the Control Center > Connections menu, and left-click on “disconnect” that appears to the right when hovering your mouse over any active connection
• Next, reset your instruments by navigating to the Control Center > Tools > Database Management
• In the Database Management window, under the “Update instruments” section, ensure that “General properties”, "Futures expiries" and “Symbol mappings” options are checked and then click Update
• Lastly, restart NinjaTrader for the changes to occur
