i dont have the Redirect subkey.. but i probably deleted it.
make two DWORD subkeys in Contrast,
one named Group with the value of 1,
another named Hide with the value of 0.
when youre done, it should show Group and Hide along with Redirect.
try resetting and seeing if the Contrast app is in your Settings / System tab..
if not, id go back and delete the Redirect subkey and try resetting & looking again.
