WP Stats: not able to log in

Hi,
I have been using the WordPress.com Stats PlugIn for some time and never any trouble from it, until I cleared ALL the private data through FireFox, now I am unable to login to the stats plugin and see, here are the things I have tried:

Unistall
Disabled it, Reabled it,
Cleared my private data again
Closed Firefox, Restarted FireFox

I have been able to log in to the stats on my wife’s side of the computer.

Any Ideas?

Thank you
Hugh
