Unable to Play

Here's how it's going, I've downloaded everything properly, and the game loads well. I can log on, I've played before, and everything was fine. But after the massive amounts of lag, March 27th I believe it was, I haven't been able to get farther than the character select screen. I've logged on well enough, and I type in my pin but then the program closes talking about a server error. I've tried quitting and logging back in, I've tried re-downloading and re-installing. I've even tried another account. None of this has solved my problem. Any and all assistance would be appreciated. Thanks in advance.
