I think I buggered up CCC something fierce. I'm not sure what happened, but when attempting to upgrade from 10.4 to 10.7, the installer kept giving me the error "Install Package Failure!". I'm not sure how it failed, exactly, as the drivers are here, installed just where they're supposed to be. It might have something to do with the fact that I ran Phyxion.net Driver Sweeper to wipe all traces of 10.6 so I could revert back to 10.4 because 10.6 had a problem with OpenGL games. But that doesn't make sense because 10.4 re-installed just fine with no problems, and CCC ran OK.
Does anyone know what to do in a situation like this?

When I'm facing problems like this one, I always reinstall WIndows.
