Hello cls71,

Please send an email to platformsupport [at] ninjatrader [dot] com. In the email please include a link to this forum thread.

Hi Chelsea

I already sent you the trace file.

Every day I still have these exceptions several times as I write code - both in the Ninjascript editor and VisualStudio 2015 - that cause NT 8.0.8.0 shutdown.

Hello cls71,

Thank you for your response.

Based on the excerpt you provided from the trace file, I would suggest a repair of the installation. The ActiPro items listed in the exception would suggest ActiPro needs to be reinstalled, which is performed when NinjaTrader installed.

Please follow the steps listed below to completely uninstall and reinstall NinjaTrader.

• Close all running applications.
• Uninstall NinjaTrader within Windows Control Panel.
• Reboot your machine.
• Once these steps are completed, download and install NT8 from the link below.
• http://ninjatrader.com/PlatformDirect

Please let me know if the exceptions occur and if so please send us your full log and trace files.
