As of lately a lot of my friends have been getting booted constantly with a 90,001 error. Does anyone know what causes this, what fixes this, or any information at all as to what could be the culprit? At least one of them is nearly ready to quit the game, they're so bad, and her pc is brand spanking new, new modems, new router, new cables, but still persisting to have this same error over and over.
