Asus Net4switch uninstalled : administrator account broke !

I installed Net4switch (suggested by "Asus Live Update" software) in january 2011.
I tested it the 04/03/2011 (ran it once) then uninstalled it less than 1 hour later.

When Windows 7 (64 bits) restarted I had a big issue : my Administrator account is impossible to use ! (can't login, error impossible to load the profile <OK>).

Do you have heard about this issue ? (I have an other account, simple user, but administrator tasks don't work (nothing happens after entering administrator password)).

When Windows load, after typing Administrator password :

"Failed to logon service Service user profile.
Unable to load user profile.
<OK> "

(translated from French)

Under Windows, logged with my second account (simple limited user) when I try to run administrator tasks :
Nothing happens after typing Administrator password (applications asking administrator account don't lauch (ie : Windows's users manager...)).

Thank you for the tip, however this is something I have tried and that does not work : at the step 2 ("Manage another account") when I type the password of the administrator account nothing happens, none new window do open.

On my next computer I will create 2 administrator accounts ;)

I will use "System Restore", but before I try to get a clean solution to the issue.

I had my response from Asus.

I tought they would provide me a "sharp" technical solution, but their reply is :
Boot, press F9. "Windows setup", then recovery windows to enter Hd with 2 partitions" !!!


My solution :
- After I tried a Windows boot F8 / last good configuration known => same problem.
- I did a restore from a TrueImage image backup I done in january.
