Hi Chandrakant,
This could be caused by a couple of different reasons.
You could try first of all try a cold reboot.

Should this not work it could be an issue with multiple licenses. The license manager takes the first relevant license it finds. Not the highest tier.
You could check if there is no expired trail license sitting somewhere in the background.

Should this not work you could try to remove all licenses connected to the test executive and then add them again.
If this does not work you can have a look at reinstalling the test executive. (make sure to remove the license before uninstalling, had some bugs with this in the past)
If all these steps won't work I would recommend contacting NI. Their tech support will always help with licensing issue regardless of active SSP or not. (a.k.a. free licensing support)
Hope it helps!
Kind regards,
