For the past 2 days when I finally get to log in I get the 90000 error with in Minutes of playing and get kicked off. This has been every time since Sat at 3:00 pm EDT. Am I doing something wrong or are other ppl having this problem? I contacted support about it and they gave me this :

Thank you for taking the time to report your frustrations and concerns about not being able to get into the game due to login congestion. We understand that these frustrations are justified, since you would like to enjoy FINAL FANTASY XIV, and this is preventing you from getting into the game. At the current time world population caps are being met, which prevents additional access to these worlds. However, we are currently working to add additional worlds ....... etc

This does not help me at all! plus I wasn't even complaining about the congestion. BTW It happened this morning around 6 am EDT (non congestion time) and 8:30 am ( non Congestion time)
