Ninja Trader 6 beta 4 startup problem

[bmaltz]

Whenever I start NT 6 beta 4 I keep getting he following error message:

NinjaTrader application has encountered a problem and needs to close. We are sorry for the inconvenience.

When I click the OK button in this message box NT shuts down.

NT 6 beta 4 had been working fine. However, I just got back from a week's vacation and I now get this problem.

Thanks for the help.

Please try renaming the database to force NT using a fresh DB -> please rename file <install>\db\NinjaTrader.mdb to some different name.

NT then will put a fresh DB in place. Let's seee how that goes.

OK, Dierk,
Your suggestion worked.

The old NinjaTrader.mdb file was over 30MB in size, whilethe newly created one is only 3.2 MB. What data did I lose in making this change?

thanks,
Ben

Your old DB holds lots of data (chart data, trades, executions, old orders etc.). The new one is just blank.

Can you please mail me your zipped, old DB to "dierk AT ninjatrader.com". I want to take a look and see what could be done.

Thanks
