Post-processing not working?

[wilflare]

I'm trying to use post-processing on The Legend of Korra
I have done all the necessary setup, creating the profile, etc and enabled post-processing in the ini for LoK

However, there's no distinguistable difference in the image shown - am I missing out a step or two?

and bloom.fx seems to be missing...
EDIT: okay bloom.fx is there just that it doesn't show up in the dropdown menu
