If you have a problem with entering your in-game nickname, remember that before you enter your in-game nickname, you need to take part in a RANDOM battle.
Also remember, that the in-game nickname you enter needs to be assigned to a new account registered through Gamekit.
If it doesn't help, please write to the Support Team https://gamekit.com/contact and send:
- your in-game nickname
- the link to your profile on WoWs (http://worldofwarships.com/en/community/accounts/)
- name of the server you played on
