I've used ZD for many years and never had any significant problems with it. However, at about 11AM today I tried checking my email but could not get ZD to load. I had just upgraded my Online Armor and thought there might be a conflict. There is no conflict. In any event, I've used OA the last couple of years and never experienced any conflicts with ZD.
On attempting to load ZD, I received a popup stating the following:
"[Javascript Application]"
"Couldn't Access Zimbra Desktop Server. If issue persists after reinstall, please check logs for errors and report to http://www.zimbra.com/forums/zimbra-desktop."

Since I cannot load ZD, I'm not quite sure how to check the error logs. But I've reinstalled ZD twice and still keep on getting the same error message. I just found out about ZD 2.0.4. I will replace v1.0.4 and if I continue having the same problem, I'll update this thread. Thank you.
