Windows Live Mail – “Problem occurred while trying to open this message”

Cannot open new or old messages received or previously sent messages on Windows Live Mail. When I click the message title to open, the following message comes up "A problem has occurred while trying to open this message. A problem has occurred. Please try again" The same message comes when you click the message again to try again. I also cannot send emails. The computer is operating on Windows 7. My address book is also now empty. I can access the info through my other devices not running on Windows Live Mail. This just happened when my computer shut down due to a power failure. When my computer was restarted, the problem occurred. How I can fix this problem and reaccess my address book.
