That's good. 7 usually installs drivers automatically. Knowing that the only thing you'll be downloading is the driver utility to customize the pressure sensitivity and such. Is that what you're having problems with?
Oh I think the problem's solved! I tried downloading multiple drivers from the page you linked, and apparently one worked At least finally the pressure sensitivity's back. Phew! I did a complete reset of my computer yesterday, and it's been acting strange since then. But it's done over 200 updates during the latest hours so I guess it's finally back on track again.
