try uninstalling and re-installing the driver (CCC).
i tried editing my post to add in what i had already tried but it wouldn't let me not sure why.
anyway here's what i've tried
reinstalling a dozen times using,
the amd uninstall option,
different versions of CCC (including a beta)
deleting the assembly files (but my comp didnt have any of those)
checking the registry for left over files (werent any)
tried uninstalling in safe mode and then installing (in normal mode as you cant do that in safe mode)
none of these fix it.
