So, I was among the many people getting the launcher issue that's asking for you to register again. Found the solution and I'm going to post it in hopes it'll help some people who haven't tried it yet. I'm not sure how this would work for the PS3 version, but this one is for PC. Anyway


Step 1: Check your e-mail. I got another code from the place I pre-ordered from about 4 days ago, and didn't really bother to give it more than a skim over since I thought I was good to go. It'll be another 20 digit code.

Step 2: Google Mog Station and it should be the first link. Log in.

Step 3: Click on Account Services, then choose Windows PC (or I guess PS3, but again I don't know if that one'll work since I'm on the PC version)

Step 4: Input your code that you got in your e-mail, click next. Make sure everything on the next page looks correct, it should say you get like 30 days of playtime. Click next!

Step 5: Click the launcher, It'll still have that message up, just say you currently possess an account, log back in and you should be good to go!

If the problems still persist, then it might just be something else happening with the launcher. By doing this I was able to log back into the game, so I hope this post helps somebody else!
