Cannot connect to IB anymore after pc crash

[Cugel]

Hello,

after my pc locked up and I had to press reset, NinjaTrader cannot connect to IB anymore. Here is what the log says:

01/03/2010 11:40:43 Connection Interactive Brokers: Primary connection=Connecting, Price feed=Connecting

01/03/2010 11:40:44 Connection Interactive Brokers: Primary connection=Connected, Price feed=Connected

01/03/2010 11:40:45 Default Cbi.Connection.ProcessEventArgs.ConnectionStatusEv entArgs.Recover/Reset: Mapping: IObjectHelper is missing Instruments_ : NinjaTrader.Strategy.StrategyData

01/03/2010 11:40:45 Connection Interactive Brokers: Primary connection=Disconnected, Price feed=Disconnected

Please don't tell me I have to use other versions of NT or TWS, because before the crash everything worked perfectly well for many months.

Regards

Cugel

Edit: I have already deinstalled and reinstalled TWS and NT. Didn't help.

Cugel, our official TWS / NT version recommendations would still stand as per our guides -

However, this looks more to be an issue with your database file after the crash, please try the Repair / Reset option under Tools > Options > Misc and then see if you can reconnect.

Thanks

Bertrand,

Reset DB worked. Thanks a lot.
