Vista - Unable to log into own user profile (administrator) - fail User Profile Service

Hi guys
I have Windows Vista Home Premium loaded in my laptop. So far all is well until I turned it on today and attempted to log into my profile. On my computer, there are only two users set up - Mine (administrator) and Guest (limited access).
While trying to access my own account, the systems says it is unable to access User Security System Profile.. or something along that line. Then it denied me access and subsequently the 'Logout' sign came on and it returned back to all the users selection.

Last night, prior to shutting down, the new Messenger Live was downloaded.

I have tried to access the Guest account and 'Manage other accounts' by entering my password, but nothing is happening.

I have tried everything that I found on Microsoft forum...including renaming the profile file name in Regedit (unable to do so - error message appears that I cannot rename)...

I'm a little worried about the 'delete' profile instruction. When I do so, and following the rest of the instructions (i.e after deletion, log on to computer and create a new profile), will my old profile come back or will I lose everything?

Besides..if I delete the ONLY administrator account, how am I suppose to create another account?

HHEEELLPP

Can you please tell me what is going on and how do I get back into my profile?

Thanks

Do not delete anything! If you delete your old profile, it will be gone! I
don't know where you saw whatever you tried, but usually it is impossible
to restore a corrupted user profile. However, you can save the data -
documents, pictures, music, emails, favorites/bookmarks, etc.

And now you know why creating an extra administrative account is important.
You will need to enable the built-in Administrator account (disabled by
default) using a third-party rescue disk like NTpasswd.

1. Download the bootable CD .iso, burn with third-party burning software (as
an image, not as data), boot with the media you created. You may need to
change the boot order in the BIOS or get a temporary boot order menu with a
special keypress. NTpasswd will run. Follow the instructions carefully and
enable the built-in Administrator account with a blank password.

2. Now boot into Windows. You will see the newly enabled Administrator
account on the Welcome Screen. Log into it and go to Control Panel>User
Accounts and:

a. Create an administrative account to be used only for elevation and
emergency purposes in the future (like this one was!). Call it "CompAdmin"
or "Tech" or the like.

b. Create a Standard user account for your daily work. You should not run as
administrator for security reasons and this is easy to do in Vista.

3. Now log into your new Standard user account so the profile folders will
be created. Log out.

4. Log into "CompAdmin" and:

a. Start Orb>Search box>type: cmd
When cmd appears in the Results above, right-click it and choose "Run as
administrator". This will give you the command prompt. At the prompt, type:

net user administrator /active:no [enter]

Close the command prompt. This will disable the built-in Administrator
account again.

b. Using Windows Explorer, copy the data from your old corrupted user
account to the new Standard user account you made for yourself.

If you can't do the work yourself (and there is no shame in admitting this
isn't your cup of tea), take the machine to a professional computer repair
shop (not your local equivalent of BigComputerStore/GeekSquad).
