Note: "The High Frequency Update is by default turned OFF in this release. You will have to enable this setting to take advantage of the improved networking. To support players with a limited bandwidth connection, we support three different levels: LOW, MEDIUM and HIGH. Most players with a connection faster than 1Mbit upload and 1Mbit download should be fine using the HIGH setting. If you experience any issues, lower or turn off the setting completely."
Will try it later tonight...
