Delink account from steam

Im trying to delink one account from steam so that i can link another one. i have already tried deleting the account that is linked with steam but it made no differance. its still linked and whats more odd, all my progress including ships, levels and equiptment are all still on when i sign in through steam. Is it possible to delink this account? any help would be appreciated, thank you.

Interested in knowing this too, just how exactly we can delink/unlink an account to steam.

Deleting the account should be enough, honestly.


Going to try and install the game via the homepage instead, and see if that makes a difference.

EDIT: Well, works that way. Running on a new account now.
