If you are using the same username and password to post in the forums, everything should be working with no issues. If this by chance is a separate account and you use a different one to log into the game, if your password is longer than 14 characters, try only entering the first 14. Currently, we only support 14 characters or less.
If that still does not work, try clearing your IE cache (launcher uses IE no matter what browser you have set to default). If that still does not work, you'll want to reach out to customer service. Details here: http://sto-forum.perfectworld.com/sh...d.php?t=267893
Hope that helps
Those of us with the Cryptic Accounts during that Linking thing got hosed having to change the login of the Cryptic Username to the PWE one every time we login/switch characters I put in a ticket and they just said they were aware of it and has been over 3 weeks now with no resolution.
