major crashes -- error messages attached

[werido]

Hi, my NT crashed and I've repaired, then uninstalled and redownloaded and reinstalled but it still gives me the same error messages attached. I did put the NT folder as an exception in my antivirus as per a previous suggestion to solve a crash I was getting at midnight. But now I can't even start NT. All I get is the error messages. How do I get back online?

Hello werido,

Can you please repair the database. The error message indicates the current database is corrupted.

-Disconnect NinjaTrader from any open connections via File > Disconnect
-From the NinjaTrader Control Center window select the menu Tools > Options
-Select the "Data" tab
-Press the "Repair DB" button
-Press the "OK" button

If the error remains, please rename the database and check again.

-Shutdown NinjaTrader and Go to the Start Menu
-Select My Documents--> NinjaTrader 7--> DB--> NinjaTrader.SDF.
-Right click on NinjaTrader.SDF and select "Rename." *Name it "OLDNinjaTrader.SDF."
-Then restart the software and NinjaTrader will create a fresh database file to use
-Unfortunately the following items stored in the old database will be lost:– ATM Strategy templates, Session templates, Instrument Lists / Custom Instruments and historical trade execution data

To prevent running into situations where you can potentially lose important data, we advise to run regular backups via our inbuild backup feature in NinjaTrader - http://www.ninjatrader.com/support/h...up_archive.htm
