i had the same problem. i couldnt get it to go away. using uninstall, registry cleaner, driver cleaner, etc. i basically went from 8.2-8.3->8.2(had the CCC prob like u)->8.1(still had the prob)->8.2(still had prob)->format c:->8.2 (works!)->8.4(works even better)!
I have had the same problem try uninstalling drivers and in SAFE MODE use a driver cleaner then reinstall i had best luck with cat 8.1 and 8.4!. Also i have heard and seen problems with SP3. good luck lett us know what happens
