GPS won't start anymore !

Hi list !

I'm a new user of GPS on windows, I've been using it for 3-4 months now, 
it's been working like a charm, but now, it won't start anymore !!

I've tried de-install re-install. I've deleted the .gps dir, i've 
checked the windows registry, but there doesn't seem to be any config in 
there for GPS.

I'd be glad if someone could help with this ....

THX,
Floof
