NT8 Won't Start

[sylvestersergio]

out of nowhere (actually after installig latest Jigsaw Daytradr version) NT8 is not starting and crashes after this message appears:

unhandled exception could not load type 'Ninjatrader.NinjaScript.Indicators.CumulativeDelt aType' from assembly 'NinjaTrader.Vendor, Version=8.0.12.0 Culture=neutral, PublicKeyToken=null'.

I have unistalled it, reinstalled it, and the same thing happens.

help!

Hello sylvestersergio,

Thank you for the post.

This error would indicate a problem with versions being used. Can you tell me, are you on the current release of NinjaTrader?

The error is specifically mentioning version 8.0.12.0 which is fairly old. If this is the version of NinjaTrader you are using the vendor has likely exported the script with a newer version of NinjaTrader which creates a conflict.

The solution here is very likely going to uninstall this item and ensure you are in a compiled state. Then update NinjaTrader to the current version and re-import the item after doing so.

If you are on the current release, you may need to check with the vendor that this item was exported for NinjaTrader 8.0.15.1 as that is the current release.

You can update the platform by going to https://ninjatrader.com/PlatformDirect and entering your license key to download the installer.


I look forward to being of further assistance.

What do you mean by uninstalling that item? NT8 or the indicator?
if you mean the indicator I can't even start NT8 so how can I uninstall the indicator?

What do yuo mean by compiled state

Jesse was referring to removing the custom add-on. When you say, "I have unistalled it, reinstalled it, and the same thing happens." are you referring to NinjaTrader or the custom add-on?

So we can further diagnose your system, please start NinjaTrader in Safe Mode.

Safe Mode will prevent NinjaTrader from:

• Loading workspaces.
• Connecting on start-up.
• Loading custom assemblies.
• Getting instrument updates from the server.

To enable safe mode, please use the following steps:

• Exit NinjaTrader.
• Hold the CONTROL key and double click the NinjaTrader icon.
• Keep the CONTROL key held down until you see the Control Center.
• You can verify you are in safe mode by going to Help -> About.

What version of NinjaTrader 8 are you using? Please provide the entire version number. This can be found under Help -> About (Example: 8.0.X.0)

Are you able to follow Jesse's instructions in safe mode (remove the add-on, compile, ensure you're on the latest version of NinjaTrader 8, check with vendor regarding the error you quoted)?
