I am having the same issue I'll be in the middle of playing and I'll just get booted 90k error and when I log back in I'll get the 2002 error code. The weird thing on my end, I don't have any lag every thing is just running smooth and I'll just get kicked. But it's happening every 30mins to an hour with me. Everything else on my net is running perfect and this just started last night. So hoping they do something soon.
