SE already sent email saying I have to restore access to steam client before being able to play, but steam support isn't replying for 2 days now.

Is it possible to get new steam account, buy the license and THEN use my login credentials to access an account that's been linked to my other steam account? I know that's a bit of a hipshot, but I'm going nuts here and wonder how to solve this. Wish there was a way to unlink the game from steam, but apparently that's not possible.....
