If NinjaTrader just showed you this popup:

"Vendor Notification — A license is required to use CoderForTraders VIP Plan"

— and all your tools stopped loading right after you started trading with a prop firm, nothing is broken. The fix takes a few minutes.

What happened: prop firms often set up your NinjaTrader account under a different email than your regular one. Your tools are licensed to your NinjaTrader account email — so when NinjaTrader runs under that new login, the tools won't load. You'll get this license message after joining a prop firm whenever the firm gives you its own NinjaTrader login. It's nobody's fault — not yours, not theirs. Just two identities where there used to be one.

The fix: submit a request through the support form with the email of the NinjaTrader account your prop firm set up, and I'll activate your tools on it too — free, takes a few minutes. Then restart NinjaTrader and you're back.

Your regular setup doesn't change — your original NinjaTrader account keeps working exactly as before.
