Our devs have been busting their butts to get a compatible "Live" client working, and after many days of work they have it mostly compatible - at least enough to log in and try a few things. I have updated our LoginServer and EQ2TC to allow these client versions to connect, so give it a try if you like using the latest EQ2 Live Client (12/12/2012).
Note: All bugs reported using CoE clients will be ignored, because we're not ready for CoE testing just yet. Keep this in mind when trying out the CoE client, as we already know they are not working perfectly
