LOST CALENDAR INFO!

Dear Sirs, I recently this week lost all my posted Calendar Info. The info was posted on every Sunday Night and when I checked yesterday and today, From May 30th 2010 to Sept. 26th 2010, has been wiped out! What can I do in order not to have to manually repost that whole schedule back up again? And Why did it dissapear? Here is my site http://americansocomleague.simplygaming.org
You can see by clicking on the May Calendar date of the 30th, there is no schedule posted. Help!!
