Today the download for upgrading to OSGrid version 0.7 is up as are the instructions and a warning NOT to go online with the upgrade. Wait until the server change over is complete Sunday. The upgrade will NOT connect until then. Attempting to connect with the upgrade will cause problems. Wait.
Instructions are here: Upgrade procedure for upgrading your simulators to OpenSimulator v0.7 on OSgrid
