We are not in charge of E6 license. We can't remove it for you, you could contact E6 to get some assistance for that.

It seems like you are in a situation that you are using the Demo license that is provided for free instead of our provided license. 

Please go to the manual that we've provided and follow the exact step to activate your license. After you've followed the exact steps, you could remove the demo version and successively activate the license we've provided.

Thank you.

I’m in demo mode. It won’t redeem or activate my license. It says it’s already in use. Can you remove all the licenses from my account  please
