Import Error - The NinjaScriptArchive File may contain duplicate method names...

[preqc]

I have attached a screenshot of the full error message.

I've uninstalled & reinstalled NinjaTrader, I've deleted every other 3rd party indicator & I've tried compiling files in the NinjaScript Editor but none of this has worked.
Any suggestions on where to go from here?

Thanks.

Hello preqc,

The error indicates you have a NinjaScript file present in NinjaTrader that uses the same method names as the NinjaScript file you try to import. Do you have any other indicators or strategies installed that are similar? Unfortunately I cannot tell what other indicator or strategy contains the duplicate method names. If you have an older version of this NinjaScript already installed, please uninstall the old version first and then check if you can import it. You can delete indicators and strategies at Control Center-->New-->NinjaScript Editor.

If the issue remains, I suggest to proceed as follows.

• Shut down NinjaTrader.
• Navigate to the Documents folder in Windows.
• Right click the "NinjaTrader 8" folder and select Rename. Name it "NinjaTrader 8 Old". This folder contains all settings and data.
• Uninstall NinjaTrader via Windows start menu-->Settings-->Apps.
• Reinstall NinjaTrader from the link below.

You will have a fresh new installation without any of your settings and data. I assume you can now import the NinjaScript file successful. If so, please shut down NinjaTrader and you can manually restore settings and data between the newly created "NinjaTrader 8" folder and "NinjaTrader 8 Old" folder. I have included some file locations below.
