Sometimes KM will have an error when it quits and starts a new profile on the next startup. Look to see if you have an older profile folder. If so, your bookmarks should be there as well as your settings.
If a system error (skan disk run...) damages profiles.ini then the current profile is not found anymore. K-Meleon then starts a new profile.
Go to the current profile directory (Edit, Configuration, Profile Directory) then move up one level and You will find another (or more) profile folder.
Move into the folder and open bookmarks.html with a browser. You may have to repeat this for each old profile that You can find.
If the file contains the bookmarks of Your last used profile - You found the lost profile and data.
You simply copy all the data/files from the lost profile into the currently used profile and restart the browser.
p.s. On very rare cases skandisk ruins files inside the profile folder.
You can try to salvage individual files.
Another rare case is that an existing profile.ini is deleted. That changes the location of the folder where the profiles are generated. That file is only used rarely for portable setup and Win98. Please inquire if this is the case.
