I have been troubled by this message on my computer, for past few days, when I attempted to start it: ( ....I knew this was going to happen again when the Computer said, it is "Preparing your Desktop...." while starting. Then you get this error message!
This meant all book marked pages, all settings, saved passwords and user names, Incredimail/Thunderbird/Mozilla Firefox are all like you are using them for the first time- nothing is saved, and nothing can be saved now, until you solve this problem.
At first a restart helped, but the same thing happened again next morning.
For other Vista users, or anybody else who is facing the same problem, the solution was found in Vista Forums, at http://www.vistax64.com/vista-installation-setup/79208-vista-user-profile-not-loaded-correctly.html
AND THE SOLUTION,
Go to Computer - Vista C- Right Click - Choose Properties - Tools - Check Now - Scan for and attempt recovery of bad sectors- Choose Start and wait for around half an hour. When it's done, restart your computer. Hopefully it will restart normally :) Mine did.
