I have to keep activating my account?

[Parry_Harry]

Hey guys, I recently bout M&B  and i started playing nord invasion with a friend but even after i registered and activated my character every time i join a different game it says that i need to activate it again. its getting rally annoying so any help would be good.
Thanks
also when i activate my account again i get a red shirt but if i leave and rejoin or join a different server it will take away the red shirt and restart my account
