@hvbog, if you are running Win 7 with shadow-copying enabled, you may be able to recover the bookmarks file from an earlier timeframe. You locate the bookmarks.adr file in the file Explorer, right click it > select Properties > select Previous Versions tab > wait for any previous versions to appear on the listing (it could take many seconds, for a large file structure). If they do appear, select one from a hopefully "safe" earlier time point and restore it. A lot depends on whether your Win installation has shadow-copy enabled, the size of the shadow-copy storage space allocation on the drive, and how much file "churning" has occurred... when the shadow file gets full, it pushes the oldest files off to make space for the newest.
