NT8 Unusable, Unable to Repair DB

[trilliantrader]

Hello. I had strategies running the other day and our internet connection went out for several hours with no warning. Ever since, I cannot get NT8 to stop throwing errors.

Specifically, it seems to be happening with NQ data because when I load an NQ chart, it does not load new data and says "Loading..." in the upper left.

When I attempt to repair the database, I receive this error: Failed to repair DB: Specified cast is not valid.

I have created a new workspace, updating/uploading add ons (Flowbots). Is there any hope to save this installation?

Hello trilliantrader,

Thank you for the message.

This behavior has been resolved in the most recent update to NinjaTrader.

Please follow the steps below to update to the most recent version of NinjaTrader 8, version 8.1.3.0:

• Login into your NinjaTrader Account Dashboard
• Click "Download" in the bottom left-hand corner of the sidebar
• Select "Download" in the "Most Recent Release" section
• Once the installation is downloaded, ensure any previous version of NinjaTrader is closed before running the installation package.

After updating, please use the following steps to rename the database file so NinjaTrader automatically creates a new one:

• Close NinjaTrader
• Go to Documents folder > NinjaTrader 8 > db > NinjaTrader.sqlite, right-click on this file and select 'Rename' and change the name to "NinjaTrader Old.sqlite" and then click off of it anywhere to save the name change
  • Please click here for a video demonstration of how to rename the Database file

After completing the update and renaming the database, you can log into the platform using the same username and password as your NinjaTrader Account Dashboard.

• Note: Updating NinjaTrader Desktop will not affect any custom configurations, workspaces, or add-ons.
• A visual walkthrough of the update process may be found here in our Help Center.

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