Windows Live Mail won't start - get "Your calendar contains corrupt data" error

When trying to start Windows Live Mail I get an error message stating "Windows Live Mail could not be started. Closing Windows Live Mail. Your calendar contains corrupted data that is forcing WLM to close".

The error number is 0800010105.

I have researched this on the internet and found numerous possible solutions and have tried all of them with no luck in solving the problem. So far I have tried:

1. Uninstalling and reinstalling Windows Live Mail.

2. Running repair on Windows Live Mail.

3. Checking the date and time and unchecking the box to adjust for daylight savings time.

4. Deleting the Calendar folder under the Windows Live Mail folder.

5. Deleting my Hotmail Calender on the web and creating a new calendar.

6. Creating a new user account and running Windows Live Mail under that account (same result).

7. Resetting Internet Explorer to the default settings.

I am including the WindowsLiveMail.log file as follows:
