Licence removed on startup- NT8 defaults back to SIM

[doc4978]

This has happened twice now

My install of NT8 defaults back to being unlicensed when I start it up. I get the "getting started" pop up as if I'm installing and using for first time. When I check the licence, it has a SIM one in.

Note,

-It has kept my templates/profiles- but my configured time settings (eg 240 mins) all gone
-I have tried flushing dns as an admin then restarting
-I use a VPN (hasn't been an issue before)

Hello doc4978,

Thank you for your request.

From the description that you've given, it sounds as though your Machine ID may have changed. If your machine ID has changed, NinjaTrader 8 will automatically remove your license key, username and password, and other sensitive information. This is a purposeful security feature. This feature prevents others from being able to access your personal information simply by stealing your files and loading them onto another PC.

NinjaTrader does not control your machine ID directly. Your machine ID is generated by NinjaTrader based on your PC's fundamental hardware (like RAM, motherboard, etc.) and fundamental software (BIOS/UEFI version, Windows updates, firmware updates, etc.). If any of these items change, your machine ID is likely to change as well. There is no way to manually change your machine ID.

We can confirm this by reviewing your log and trace files. If you'd like us to review your log and trace files, you can send us an email from directly within the platform by going to Help > Email Support with a brief description of the issue in the body and ensuring 'Log and Trace Files' is checked will include these files. This is checked by default.
