Licence not accepted — troubleshooting

"Invalid License", "License expired", "Wrong account" — what to do about the most common licence errors.

"Invalid License Key"

The key is not recognised. Common causes:

  • Typo: transposed letters or spaces at the start/end. Copy the licence from the confirmation email again.
  • Wrong product: You entered the key of product A in product B. Check in the Library which licence belongs to which product.
  • Key revoked: In the event of a refund/cancellation the licence is deactivated. Write to us if you are sure the key should work.

"Wrong MT5 Account"

The key was activated on a different MT5 account and is bound to it. Solution:

  • Activate the EA again on the original account, or
  • Write to us at support@tmb-invest.de with your licence and the new account number — we release the binding manually and you can activate on the new account. This is free and usually takes at most one working day.

"License Expired"

That doesn't happen with products bought outright. If you get this message, write to us straight away — usually it's a bug during activation. With POOLS rentals it's normal: the licence expires with the rental period, and you can extend it via the MQL5 store.

"License Server Unreachable"

The EA cannot reach our licence API. Common cause:

  • Firewall blocking: In MT5 Tools → Options → Expert Advisors → "Allow WebRequest for listed URL" — add https://tmb-invest.de add.
  • VPS/server without internet: If you run the EA on a VPS, check whether outgoing HTTPS connections are allowed.
