Unfortunately . . .
Last I checked, the creator/maintainer of CWShredder had announced EOL for the utility. Some people have made noises about being willing to take over maintenance of the thing, but I would say you shouldn't expect the same ubiquitous, nigh-infallible performance from it as you previously could, because new CoolWebSearch versions probably won't be addressed as effectively or as quickly as they once were.
C'est la vie. The world moves on.
