We are aware of an issue that prevents the upgrade screen buttons from appearing.
Please use the red hang up key on your BlackBerry to return to the main home screen. Open a browser and go to
http://m.astrasync.com and you can then download the upgrade directly.
Unless you were previously on 4.2.11 you will not need to uninstall to upgrade.
