Wacom Tablet Win7

I have a wacom graphire 4, I use win7 home premium 64-bit.

I noticed one day that when I drew with it, the lines came out jagged no matter how smooth my actual drawing was. No tweaking of the preferences would remedy this. So I figured I'd update to the latest driver software.

I cannot get the tablet to work with the latest driver listed on the site.
it would not recognize that the tablet was there.
so I uninstalled it. Then installed the 2nd newest driver.
Same.
Uninstalled. Installed 3rd newest driver.
Uninstalled. Installed the oldest driver, figuring that the problem arose some time in the newer drivers.
That would bring up the preferences, but any change to them did not affect the tablet's behavior.
Uninstalled. Installed 2nd oldest, 3rd oldest, 4th... no luck!
the light is blue and just blinking. When I touch the pen to it the light turns green. it just behaves as if there is no driver software.

What should I do?
