Hi,
This sounds like TP Connect is presenting the trial mode nag screen during a live mode connection. This indicates that TracerPlus connect is treating the device as in trial mode because either the device is not registered and/or TP Connect is not registered.
If there is a way to send over a screenshot, I can confirm this, but that would be my bet.
I recommend double checking the registration status of both the PC (TP Connect) and the device itself.
