Hello EngineerHTM ,

Thank you for reaching out.

This error may occur if your database file has become impacted somehow. From the error, it may mean that your security/file settings have certain document files set to read only or restricted.

In any case, if you wish to reset your database, you may do so manually:

You may rename your database to resolve this using the following steps:

• Shutdown NinjaTrader, and navigate to the Windows File Explorer (Windows Key + E)
• Go to the Documents/NinjaTrader 8/db folder
• Right-click on "NinjaTrader.sqlite" and rename it to "NinjaTrader OLD.sqlite"
• Here is a reference video: Renaming the Database File

When you restart NinjaTrader, a fresh database file will automatically be created by the software. You should then be able to connect and your Charts should be loading properly.

• Unfortunately, the following items stored in the old database will be lost - custom Trading Hours templates, custom Instruments/Instrument Lists, historical trade execution data, and saved Strategy Analyzer backtest results
• Locally added Sim accounts will be removed, Sim101 will be reset, and any strategies will need to be re-added to the Strategies tab

To prevent running into situations where you can potentially lose important data, we advise running regular backups via the built-in Backup feature in NinjaTrader.

Please let us know if we can be of further assistance.
