@games2056g 

only one swtor account can be linked to a steam account at any one time, same for the steam account

I know but I'm linked steam account for SWTOR account but i can't login to account

If you log into that swtor account at www.swtor.com and click on overview , does the steam button show any linkage ?

Your best to call swtor support when the lines are open and see if they can work out what has happened, that message indicates that swtor account is not linked to that steam account
