My Replikanto has disappeared. What could be the cause?

If Replikanto has disappeared from your NinjaTrader workspace — the indicator, add-on, or window no longer appears, or NinjaTrader shows the license as invalid — the cause is almost always one of three things: a machine ID change, Replikanto not being loaded with the workspace, or a NinjaTrader update that broke the installed add-on. Work through the causes below in order.

Cause 1: A machine ID change invalidated your license

Replikanto's license is tied to your NinjaTrader machine ID. Changes to your computer's BIOS/UEFI version, a Windows operating system update, or a firmware update can change that machine ID, which invalidates the license. When this happens, NinjaTrader shows a window on startup indicating the license is invalid.

• Go to the License Manager page and update the machine ID.
• There is a 2-hour waiting period after a machine ID change before you can change it again.
• Restart NinjaTrader after updating the machine ID.
• If Replikanto still doesn't work, send a screenshot of the invalid license window when you contact support.

Cause 2: Replikanto wasn't loaded with the NinjaTrader workspace

Replikanto may simply not have loaded alongside your saved NinjaTrader workspace.

1. Try opening it manually: go to New > FlowBots > Replikanto.
2. If that window doesn't open, Replikanto may not be installed correctly — repeat the installation steps.

See How do I install a FlowBots NinjaScript (Add-on, Indicator, SuperDom Column or Strategy)? for the installation walkthrough.

Cause 3: A NinjaTrader update broke the installed add-on

NinjaTrader updates can interfere with installed add-ons, causing Replikanto to fail to load. When this happens, you may see an error message such as Could not load file or assembly when starting NinjaTrader.

1. Download the latest Replikanto installer from your FlowBots account downloads page.
2. Close NinjaTrader completely before running the installer.
3. Run the installer and follow the setup steps.
4. Restart NinjaTrader after the installation completes.
