Be sure you understand the Supported Versions of NinjaTrader for MTM
NOTE re Machine ID: From time-to-time, your NinjaTrader 8 Machine ID may change. This can be caused by software and hardware changes to your system.
Your MTM licence is created using your current NT8 Machine ID. If your NT8 Machine ID changes, your MTM licence automatically becomes invalid, and you will not be able to use MTM until you install an updated MTM licence created with your new NT8 Machine ID.
If your NT8 Machine ID has changed, use this form here to send your new NT8 Machine ID to Mizpah Software. We will create a new MTM licence for you and make it available for you to install, usually within 24 hours.
This MTM licence update is always free of charge. Note that this new MTM licence replaces your previous MTM licence and obsolete NT8 Machine ID, both of which will no longer be valid.
