Don't know what's going on with your MSE, but as for CCC
I was able to resolve that on my own system doing a complete removal of the ATI drivers
/software and then doing another completely fresh install.
I used this to remove (the uninstaller doesn't get it all) Phyxion.net - Driver Sweeper
also make sure you .net framework stuff is fully up to date as CCC relies on .net components.
