NT8 freeze

[JustJoker]

Hello,
Sometimes, when I try to change the workspace or even to modify an Indicator, NT8 freezes. One of the charts of 2 at my workspace may become transparent.
It lasts for minutes.
I close the NT, try to start again. Doesn't start and shows the enclosed message.
I have to get into the Task Manager and delete NT manually.
What to do?

Hello JustJoker, and thank you for your question.

Please follow these steps to completely uninstall and reinstall NinjaTrader 8 on your system.

• Download a fresh copy of NinjaTrader 8 from ninjatrader.com
• Close NinjaTrader 8
• • To ensure NinjaTrader is closed completely, please press the windows key (to the left of the space bar) and the letter r at the same time, and type in
    taskkill /f /im NinjaTrader.exe
    and press enter
• Rename your (My) Documents\NinjaTrader 8\db\NinjaTrader.sdf file to something unique. I prefer names that include today's date
• Rename your (My) Documents\NinjaTrader 8 folder to something else that is unique. I prefer names that include today's date.
• Use the installer you downloaded to uninstall, and then reinstall, NinjaTrader 8
• Copy these files and folders from your old, renamed (My) Documents\NinjaTrader 8 folder to your new folder. If asked to replace files, always select "yes"
• • Config.xml
  • UI.xml
  • workspaces
  • templates
  • all .dll files in bin\Custom except these :
  • • NinjaTrader.Custom.dll
    • NinjaTrader.Vendor.dll
  • all .cs files in bin\Custom except these :
  • • NinjaTrader.Custom.cs
    • NinjaTrader.Vendor.cs
    • AssemblyInfo.cs
  • any subfolder of bin\Custom that has a .cs file that does not start with an @ sign
• Start NinjaTrader 8. You will receive some dialogs about Ninja being unable to start because it needed to recompile some dlls. OK out of these dialogs
• Start NinjaTrader 8 once more

Dear Jessica,
Thanks a lot for the instructions.
I've made all you'd suggested to solve the problem.
Now it works. Will see.
But I was surprised seeing TopDog.. .dll with the newly installed NT8...
Kind regards,
Sergey
