Firewall for NT 8 -- having problems with Comodo

[vantojo]

I have a problem with Comodo Ineternet Security (firewall, hips, etc) and NT 8. It does not cause a problem with NT 7.

I get this error when trying to select an instrument from the drop down list for a chart or strategy

"Unhandled exception: The requested operation cannot be performed on a file with a user-mapped section open."

If I uninstall Comodo the problem goes away.

Any ideas? I've searched through the Comodo settings and don't see anything.

Hello Vantojo,

Thank you for your post.

Please add NinjaTrader as an exception to the condo anti-virus software.
I have linked below the publicly available Comodo site with instructions.
