Many people have this issue.
This is a very common issue as of today for a lot of players. all of which, when i ask, happen to be Comcast and Time warner users. Keta, i know, and her system requirements are not the issue at all. The issue is a communication error between their ISP and SE's server, when something similar occurs at a personal level its due to a firewall configuration, im not to familiar with the higher bigger servers though, but i dont see how this would be a hard fix. at the worst it would just shut the game down for 5-30 minutes to get it fixed, and A LOT of people that play use comcast and time warner to play. so would be a good thing to fix it asap.
