Error message, please help

This error message appears when I try and log onto ninja trader from my aws cloud.

" There only can be one instance of ninja trader running at a time (ninjatrader/2). Please terminate any other instance of ninjatrader before starting a new instance."

Does anyone know why this is happening. Last week I was able to run ninja trader on my aws cloud with no issues while my laptop ran my other ninja trader platform. Please help.

Hello dsmoots,

Thank you for your note.

Please let us know if you continue to see the same.
