Zimbra Desktop will not open anymore, and I don't know what to do here...

I noticed that a recent I Tunes update may be causing the issue as I have read, and I did install a new version yesterday.

Java updated this morning and I have to wonder if this is an issue, as well.

I am getting the following error messages:

Error: this.docShell is null
Source File: chrome://global/content/bindings/browser.xml
Line: 0

Error: uncaught exception: [Exception... "Component returned failure code: 0x80540006 [nsIApplicationIcon.show]" nsresult: "0x80540006 (<unknown>)" location: "JS frame :: chrome://webrunner/content/webrunner.js :: anonymous :: line 687" data: no]

Error: formatURLPref: Couldn't get pref: extensions.getMorePluginsURL
Source File: file:///E:/Documents%20and%20Settings/Owner/Local%20Settings/Application%20Data/Zimbra/zdesktop/win32/prism/xulrunner/components/nsURLFormatter.js
Line: 68

Does this help anyone?

I have 3 addons:

Inquisitor
Prism Runtime
Zimbra DnD

Please point me in the right direction - I am not a tech wizard, so please walk me through in understandable steps.

Thanks for helping out...
