Vista Logon problem

[Robbins]

When trying to logon on to my computer I get thr following message:
The User Profile Service service failed the logon.
User profile can not be loaded.

I am the computer admin and can not access anything. At first I thought it
was a password problem and found out that was fine. How do I get into the
system to fix this?

Hey Brink,
So you mean to tell me that profile are controlled by the User Hive Profile
Service in Vista? If so that service has to run all the time eh? Thanks

When I get into my profile , in safe mode, there is no option to create a new
account. There I get this message:
Your user profile was not loaded correctly!
You have been loged on with the default profile for the system. Please see
event log for details or contact admin.

As of this morning im getting the same problem only i have McAfee installed.
It isnt the first problem either. Their Updates are providing all sorts of
problems over the past month. I've already reinstalled and it seemed to fix
it, but then this appeared this morning. I am not all the good with
computers to be honest so this is just what i need lol.
