You may have inadvertently logged another swtor account maybe
Press the [Windows] Key + [R] at the same time
Copy the following in to the text box and press ok
%localappdata%\swtor\swtor\settings
Look for "SwtorDisplayname" _Account.ini files see if there is more then one swtor displayname listed there
Ah, so upon doing that, it shows all my account info FROM the account I'm trying to log into, including my characters, but I still seem unable to login. Would deleting the login files and trying to log back in possibly fix the issue?
thinking would be another swtor account is tied to that steam account
Best suggestion is to call swtor support and provide them any other email addresses you use and see if they can find any other swtor accounts
