Login issues.... again.

No account issue exists 

maybe untick save the displayname on the launcher and copy and paste the displayname and password from the website to the launcher

Display name is DarthPenguin.  I thought it may be a security key issue, but the security key works just fine when logging into the SWTOR website to view my account.  I tried again tonight but was unable to log in on this account.  I am using the exact display name, password, and security key that allowed to me to login to the SWTOR website to view my account....  On this account no matter what PW I use, it tells me that login service is unavailable.

I was eventually able to log in on my other account, which does NOT have a security key, but that seemed to just be a login server issue, since I used the exact same display name and password for that one both times, at first it kept throwing an error, but 30 minutes later, with nothing changing other than the time, it worked.  Tonight, however, on this account, if I get the password correct, it tells me login service is unavailable, but if I type in a different password, it tells me that the display name, password, or security key are incorrect.

copy and paste the displayname from the website login , in case there is a typo or invalid chracters being entered 
invalid characters can result in the login unavailable message your getting, eg numbers are not allowed in displaynames 

what is the displayname i can check to see if their is any account issues or not when the swtor team captains are available in about 9 hrs
