I have the same issue. I pre-ordered and have the beta key but it tells me that the beta key has already been activated and cannot be used again. It was not applied to my account because I am fairly sure I wasn't logged in to my account when I submitted the key at www.startrekonline.com/betacard. What can I do to fix this? Any help is appreciated.
Ozerati, you seem to have gotten your key sorted earlier this morning. Josh211a, nannerslug, TheSmokingMan; none of you have open beta or pre-order keys applied to your accounts. You will need to do this before you can access the launcher.
coderanger: I tried to apply my beta key to my account but it says that the key has already been used. I'm thinking that maybe I too wasn't logged in when the key was used (why you are able to use a key without being logged into an account I have no idea). I sent in a trouble ticket, but so far haven't received a response. Any help you can provide would be appreciated.
