I've been having this issue for the past couple of days. I recently bought this game, and immediately my R and S were on the fritz. And at random times, the 3002 error would appear. Today I can't play the game for more than 5 minutes at a time before the 30002 error appears and boots me off. I had wireless at first, but then I directly connected my computer to the router, and then the modem thinking it was going to solve my problem, but it didn't. I disabled my firewalls, power cycled my hardware but nothing works. My internet is running at 100mbps which should run the game fine, but it won't.

I'm both saddened and relieved to know that I am not the only one experiencing these issues, and that others are going through the same things as I. It's very frustrating as a customer who has spent money on the game to not even have a chance to play it because SE can't work their servers right.
