Only able to connect to IB TWS Simulation

[granite11]

Hi,

I have the following problem:
I use Interactive Brokers TWS (Build 898.4, Sep 28, 2009 12:34:25 PM) together with Ninja Trader 6.5.1000.14 Live. As I had some problems with NYMEX CL futures in NT, I was told to reset the DB. Since then, I cannot connect to my "normal" IB account, as I get the following log:

11/5/2009 11:28 Connection IB: Primary connection=Disconnected 11/5/2009 11:28 Default Cbi.Connection.ProcessEventArgs.ConnectionStatusEv entArgs.Recover/Reset: Der Objektverweis wurde nicht auf eine Objektinstanz festgelegt. 11/5/2009 11:28 Position Instrument='$EURUSD' Account='xxxxx' Avg price=1.4917 Quantity=xxx 11/5/2009 11:28 Connection IB: Primary connection=Connected 11/5/2009 11:28 Connection IB: Primary connection=Connecting Obviously, NT sets up a connection, but immediately after an error occurs and it disconnects.
I have reinstalled NT, but nothing has changed. Surprisingly, when I use my simulated account (each IB customer can get one on demand), everything works fine. But I need access to my live account!

Please help!

granite11, welcome to our forums! Did you 'reset' or 'repair' the DB?

Please delete the IB live account connection and go to Tools > Options > Misc and Repair the DB, then recreate the account connection fresh with the help of this guide - http://www.ninjatrader.com/webnew/su...ivebrokers.htm

Then see if you can connect with this.
