I see this error in your trace file:

2016-09-28 12:11:32:429 *************** unhandled exception trapped ***************
2016-09-28 12:11:32:429 Font 'Arial' does not support style 'Regular'.

This indicates that your WIndows 'Arial' font file has become corrupt.

Please download the zip file attached to this message, open it, and then drop the 'Arial.tff' into Control Panel > Fonts

Ensure NinjaTrader is shutdown

• Open the Windows Start Menu
• Type 'font'
• Click on 'Fonts (Control Panel)' which should be the first search result
• Drag and drop the 'Arial.tff' file into the open Fonts window

I've included a screenshot below of what you should see once you drag and drop the file. Please choose 'Yes' to replace the corrupted file.

You should now be able to restart NinjaTrader.
