Error in 'OnSessionStatusChanged': 'System.ArgumentException: An item with the same key has already been added. at System.ThrowHelper.ThrowArgumentException(Exceptio nResource resource) at System.Collections.Generic.Dictionary`2.Insert(TKe y key, TValue value, Boolean add) at fxcore2.O2GSystemPropertiesReader..ctor(IntPtr native) at fxcore2.O2GResponseReaderFactory.createSystemPrope rtiesReader(O2GResponse response) at NinjaTrader.Fxcm.Adapter.onSessionStatusChanged(O2 GSessionStatusCode status)'
1) Import a backtup that had a date before the error, it was not solved.
2) Create a new FXCM account, the same error. (in both separate computers).
3) Right now I will reinstall Ninjatrader 8 (I do not know if it works because the same thing happens in both computers), I'm going to do it suspecting that it could be a problem with the product key?
4) If that does not work out for me, I'll wait for your help or ask FXCM for help to see if it's their problem and not Ninjatrader 8.
Thank you very much for the help. Greetings.
