Cannot log into SWTOR on steam
I have tried installing SWTOR through Steam and log into my account. All the credentials are correct and an error message shows up saying "We can't log you in. Please double-check you're using the Steam account you usually play on and try again.". My SWTOR account is not linked to any Steam account. Tried looking for help but couldn't find anyone who had the same issue.
Your best to call swtor support when the lines are open, they can check if another swtor account is linked to that steam account, as only one can be linked at any one time
