Windows Vista issue need Help

[Barteur]

Hi Guys,

I have window Vista and I have an issue logging in my account (that is also the admin account).
Heres some details
Running Windows Vista
I have two accounts, mine (also admin) and my wife.
When I am trying to log on my account with the correct password, I have the following message: Login failed by the user profile service (This is the best translation I can do since my PC is in french) and then, cannot load user profil.
When I am logged on my wife profil I cannot create any other acount or delete them as admin but I have the right to install programs with my admin password so it seems that I have partial rights.

I don't know is this is enough information but I have a lot of important data on my user profile and I need it back.
This all started when I installed yesterday a external hard drive to do backups in case this happen, still cannot believe it.

When I called HP, right of the bat they told me to format my drive and restart everything, but this is the easy way out to everything... I am pretty sure something can be done.

Let me know if you can help
