Error 90k, 2002 And System Error Returned.

So, I made a thread about this problem on the 20th September, when I kept receiving countless 90k and 2002 errors.

The last 2 days I've been able to play with virtually no problems at all concerning server errors.

But starting 30 minutes ago I got 90k, then 2002 and yet again, a black screen telling me I need to register my promotion code and then a system error notice. I got back in once after that for about 10 seconds and it happened again.

Now I just keep getting a screen telling me to register my promotion code and a system error.
