Unable to create instance of 'NinjaTrader.Indicator.BuiltInIndicator'

[SuzyG]

I receive the following error message in the Log (highlighted in yellow) when selecting an indicator to add to my chart. It doesn't matter if it is a built in indicator, like the SMA or a custom one.

Unable to create instance of 'NinjaTrader.Indicator.BuiltInIndicator'. Most likely there is no default constructor defined or the default constructor does not work correctly: Constructor on type 'NinjaTrader.Indicator.BuiltInIndicator' not found.

The indicator does get added to the chart.Should I be concerned?

Thanks, Suzy

Are you on NT4B4 (latest)? If so you likely did not follow instructions from Ray to "clean up" you custom indicators (see announcement). Please review the steps provided bay Ray.

Worst case:
- uninstall NT
- save <install>\bin\Custom
- remove <install>\bin\Custom manually (will drop all custom strategies + indicators)
- reinstall NT6

I am on Version 6.0.0.4. Is there a more recent version? I did a complete reinstall due to another issue and removed all subdirectories.
