Hi

I upgraded to Zimbra Desktop 0.92 and am now unable to start the program and get this message as soon as I open it.

"Couldn't access Yahoo! Zimbra Desktop server. If issue persists after reinstall, please check logs for errors and report to http://www.zimbra.com/forums/zimbra-desktop."

What could be the cause of this?
I have tried reinstalling it a couple of times but no luck.
I also reverted back to 0.91 and still get the same error. Here's the error log:
