Hello,

I open this morning my NT platform and after connecting to the data provider got this error: "Failed to execute DB Job 'StrategyUpdateJob' there was an error generating the XML document. Object reference not set to an instance of an object.

And then NT started to slowdown and stop completely, frozen!! Please help...

Thanks,

Alan

Hello Alan,

Thank you for your response.

Please rename your database with the following steps :

• 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, historical trade execution data, saved Strategy Analyzer backtest results

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
