I have been using Zimbra Desktop for the last one week. I upgraded the version today. I am using Ubuntu 9.04 as my OS. Soon after installation of the upgrade for Zimbra Desktop, the follwing is the message I get. Kindly suggest further course of action.

Couldn't access Yahoo! Zimbra Desktop server. If issue persists after reinstall, please check logs for errors and report to Zimbra Desktop - Zimbra - Forums.
