Hello Yassine.Chetouani, and thank you for your question. For faster service, please begin a new thread instead of replying to a thread over a year old, even if you are experiencing something similar. Our tracking system sometimes does not notify us of replies to very old threads.

I would like to see on your system exactly what the path to your NinjaTrader folder is. Can you run this test for me and post a picture of your results?

• Press the Windows key (to the left of the space bar) and the letter r at the same time
• Type
  
  cmd
  
  in the box that comes up and press enter
• Type
  
  cd %UserProfile%
  
  in the window that comes up and press enter
• Next, in the same window, type
  
  echo %CD%
  
  and press enter
• Next, in the same window, type
  
  dir
  
  and press enter
• Grow this window vertically so that it can show everything that you typed in

To send a screenshot with Windows 7 or newer I would recommend using Window's Snipping Tool.

Alternatively to send a screenshot press Alt + PRINT SCREEN to take a screenshot of the selected window. Then go to Start--> Accessories--> Paint, and press CTRL + V to paste the image. Lastly, save as a jpeg file and send the file as an attachment.

Please, I do not want to uninstall the platform from the scratch as some friends tried, due to the indicators I have and the history I downloaded

Same thing just happened to me after a power failure while a strategy was running connected to IB simulated account

Same here. I didn't expect a power failure to affect the system this much.
