It might be in how you are saving them. Are you putting them into the toolbar or into the "bookmarks"? Have you looked at the far right end of your toolbar and clicked on the double arrow?
Do you know how to restore your system like Charityhand suggested? ie; double left click on MY COMPUTER (either in start up or on icon) then right click on it --then double left click on "properties" then click on "restore system" and then pick a date/time to restore it to. You can email me if you need more info.
