Mouse Settings don't work after installing stutter patch

[plutomaniac]

Try this(I use it to delete steam cloud data sometimes):

1) Delete Pig folder.
2) Start the game via steam and at the prompt to create a profile alt-tab out of the game and delete the newly created Pig folder (HPL.log cannot be deleted because it's being used, that's to be expected)
3) Alt-tab back in and exit the game without making a profile.
4) Start the game again and see if now the settings are Medium as you said.
