"Unhandled Exception: Index and length must refer to a location within the string. Parameter name: length"
I have tried all the following multiple times:
Repairing NinjaTrader
Uninstalling and re-installing NinjaTrader.
I have rebooted at least a dozen times, including in between uninstalls/repairs.
I am using Windows 10 Pro ver 20H2 (64-bit) - this is a brand-new installation of Windows I created just to run NinjaTrader, and I have not installed any other software on this machine, including anti-virus. I have never used this computer for any web browsing, email, etc. Just NT. Even this post I am doing from another computer.
I am running NT 64-bit, but when I run 32-bit, I get the same results.
Every once in a while (maybe 1 in 5 or 6 times) NT will run, but as soon as I exit and try to run it again, I get the error.
I also will get this error on occasion: "An error has occurred in the script on this page" with a URL I don't recognize, it is not a ninjatrader domain, and it only happens when I try to run NinjaTrader, and never came up before I started getting the Unhandled Exception error. Whether I click on Yes or No, ninjatrader fails to load.
Screenshots of both errors attached.
I would appreciate any help, as NT is now completely dead.
