Hello backtester831,

Thank you for the message.

We have been made aware of some other users not being able to open the platform if they are using some Apex-investing 3rd party add-ons.

• If you are using some Apex Add-ons, then this is most likely the cause.

The fact that you can open NinjaTrader in Safe Mode verifies that it is in fact being caused by one of the 3rd party add-ons.

• If you are using Apex add-ons, you would want to reach out to their support team to get steps and information on how to update their Toolkit and add-ons to stop it from blocking NinjaTrader.
  • 3rd Party Disclaimer

If you are not using Apex add-ons, then the next step is to remove all the 3rd party add-ons from your platform so you can open it again.

• Close NinjaTrader
• Go to the Documents folder > NinjaTrader 8 > bin, Right-click on this folder and Rename it to "bin Old" and press Enter to save the name change
• Now we need to Repair the NinjaTrader installation:
  • Go to the Windows Control Panel > Programs and Features > Click NinjaTrader 8 > Click Repair > Click Next through the prompts until finished
• Reopen NinjaTrader and check for compile errors using the steps below:
  • Go to New > NinjaScript Editor > Right-click on the background and Compile to show if there are any errors remaining
  • If yes, take a screenshot of the error messages and include that in your response.

From there, you should be able to open NinjaTrader and then reimport your add-ons 1-by-1 to narrow in on the cause of the unwanted behaviors.


Please let us know if we may provide any further assistance.
