"NinjaTrader has been blocked from accessing Graphics hardware"

Yet another problem...

NinjaTrader doesn't actively block itself from accessing your graphics hardware, so we would need more information about what is causing this on your PC. So I may accurately assist you, please answer all of the following questions:

• Was NinjaTrader working previously? Or has this always occurred?
• What version of NinjaTrader 8 are you using? Please provide the entire version number. This can be found under Help -> About (Example: 8.0.?.?).
• Do you receive an error on screen? Are there errors on the Log tab of the Control Center? If so, what do these errors report?
• Did any updates to your PC recently occur? For example, Windows or graphics card drivers updates?
• Does this persist if you restart your PC?

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

To enable safe mode, please use the following steps:

• Ensure NinjaTrader is shut down
• 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.

Once NinjaTrader has started on just the control center, please connect to a data feed then open a new chart with no custom bar types/indicators/templates and test for issues.

If there are no issues on this new workspace, please try opening the previous workspace by going to the Control Center > Workspaces > Choose your workspace.

If there are no issues, restart NinjaTrader normally and test for issues.

If this reintroduces issues, I would suggest rebuilding your workspace, adding 1 indicator at a time. Please keep track of what indicators you add back in so that we can narrow down what indicator is causing the issue if the issue returns.

Please let me know the results of this test.
