I went to check my calendar today and none of my events are visible and I can't switch between days in the single day view. When I go to preferences and accounts, the program hangs. I have tried hard and soft resets. I can't delete the google calendar and reinstall because I can't get to the preferences and accounts screen.

I know there is another thread with a similar issues but I didn't find mention of inability to access preferences and accounts. This seems like a related but different problem.
