No problem, first you click deposit button on your bittrex, and generate a new address, you can get the message(copy paste it to the public key field on TVE), and get the NXT deposit address, copy paste is to your TVE withdrawal address. Last step, request email confirmation, TVE will send you the confirmation code to your email address which you registered in TVE. Everything is solved now
Thanks for the instructions mate. I was abled to withdraw Darcus tokens from TVE down to Bittrex. It was confusing though but I managed to pull it over. Hopefully there will be more pump
