Over the past week or so, I've been constantly getting 'Error 90000' and subsequently getting kicked from the server. This is in addition to getting R0/S0 issues every once in a while.

The strange part about these 'Error 90000' is that I never get R0/S0 when it happens. The game has always gone back to normal after a maximum of one minute. 'Error 90000' always pops up when I am having no connection issues at all (other than the error, obviously). I could be in the middle of fighting something with low latency, talking to my Free Company or party with no issues, doing anything, and then the screen just goes black and 'Error 90000' rears its ugly head.
