I have been having this S0/R0 problem since yesturday. Happens after 5-10min of playing flawlessly. Have confirmed it not to be my PC and my connection to other games and websites is flawless. Have also played on the JP server without incident. My location is middle TN and my ISP is Wildblue... which is satellite, so I'm used to lag... but not to the point where it is utterly unplayable.
