Windows 7: Wacom Intuos4 problems

Ever since I upgraded to Windows 7, I have been having problems with my Intuos 4 graphics tablet. It seems as though the drivers are "uninstalling" themselves, because every time I start up, I have to re-install the driver (I don't have to uninstall the original).
Recently, the problems have gotten worse. Now, even after installing the drivers (again), I'll get no input from the tablet.

Anyone else have this problem?
Anyone know the solution?



Thanks.

Are you using the correct driver? is it a win 7 driver? do you have a backup from before the problem to restore from? do you have a win 7 dvd to do a repair install?

Yes, yes, no and yes. I guess I'll try repairing with the dvd.

Thanks for the response.

Repairing with the DVD didn't work- I still get no input form the tablet.

I'm having the same problem with my wireless intuos4... just started a thread here:
