i just got an update today the windows vista service pack 1 i think
and i restarted my computer and was able to log onto my profile
(there is my moms and mine)
but a lil while ago it said the following message when i tried to sign onto mine
The user profile service failed the logon (spelt like that) user profile cannot be loaded.
im just sure if its doing it bcuz of my new update
but i restarted it in safe mode and it let me log onto my profile
but when i restarted it not in safe mode it wouldnt let me log on
btw i have a password on mine but i type it in correctly so its not that
i can only log into my moms (which doesnt have a password)
yew are probably thinking...y dont yew just make another profile...but i cant because i have a lot of valuable stuff like vids and pictures
so yeah..
help?

I experienced that two days ago, funny enough.
I just restarted the computer (my user is admin level) and then relogged in and it worked! You may want to try logging out first then restarting. Good luck =]
