I just upgraded to version 3.3.
Since the upgrade I have been unable to open the Mezzmo UI. I double click on the Mezzmo icon and the splash screen comes up but sits at initializing for approximately 10 minutes.
The icon for Mezzmo also comes up in the System Tray but is unresponsive for right clicking on again for about 10 minutes.

After about 10 minutes, I am able to open the UI from the System Tray. The window opens but stays at not responding indefinitely.

Any help would be appreciated.
