I received an indication that I have files requiring backup. I accessed windows live and tried to access the backup system. I was asked to click on backup after installing a particular disc and received the following message, "Unknown problems are preventing backup from continuing at this time." I tried restarting the computer as asked but got no better results. I tried requesting a new and complete backup and got the same negative message. I have tried accessing help but found nothing involving this problem. Any help would be appreciated. There seems to be no fix for this problem.
