In the process of completing the upgrade from Vista, suing the Windows 7 Home Premium Upgrade Disk we lost power temporarily causing the computer to reboot. It did not restart from the point it was at during the upgrade process and thus lost all Vista info and apparently my Firefox Data. A file called "Windows Old" was created which shows some Firefox files but I see nothing to indicate or point to all my bookmarks.

I am devastated! My research files as well as my teaching aids were all organized in this old installation. Is there any hope here???
