Hello LisaK,

Comparator Fast creates a folder under your "My Documents" (folder's name is "Comparator Fast"). Unless you disabled the Automatic Backups feature, you'll see automatic backup files on "Backup" subfolder. You may double-click the most recent settings backup (to load it to Windows Registry), or open Comparator Fast, then go to Tools|Restore Settings. You'll see a list of all the backups on your "My Documents\Comparator Fast" folder (restore them from your hard disk backup first), and choose the last backup then click Restore.

If you need any further assistance, please don't hesitate contact me.

Have a great day,

Daniel
