The other day I received a pop up window to install a security update for my zimbra desktop. I clicked on all of the required tabs, but instead of installing the update my zimbra desktop was no longer there. How do I recover and restore the desktop as I had some very important emails there and now I cannot find them. When I click on the zimbra icon zimbra pops up at the bottom of the desktop for 1 second and disappears. When I go to support and I type in my user name it comes up as it cannot find it. Help. Thank you in advance.
