everytime i mistakenly try to run NinjaTrader twice or more by clicking on the icon, it gives an error saying I can't have 2 instances of NinjaTrader running at the same time.
The problem is that after this error window my workspace is completely gone, all of them. This happened more than once and it's really annoying so I believe someone else might have reported this problem and NinjaTrader support can help me solve it.
Thank you.
