In the Requirements link to the left, is a requirement to make your database allow zero dates. Not having done this might be the cause of your problem. Here is that requirement:
Make sure that zero dates are allowed in your database. Do this by setting “sql_mode=” in the my.ini file. For reference, make the current setting for this value into a comment by adding a # at the front of the line. An example of what this line might be set to is, sql_mode=NO_ZERO_IN_DATE,NO_ZERO_DATE,NO_ENGINE_SUBSTITUTION.
