http://content.screencast.com/users...b834-624e-4c35-b047-fce124f6038a/00000182.png I've installed Camptune to change my Bootcamp partition, so I can install a very large game via Steam. When I started Camptune, instead of getting the colourful slider which is its online manual, I get this. When I click on the slider, the slider jumps to 966.11GB and the Bootcamp partition to -18446743074013.29MB. Any ideas for fixes? http://content.screencast.com/users...b834-624e-4c35-b047-fce124f6038a/00000182.png System report https://dl.dropboxusercontent.com/u/5328690/MacBook%20Pro.spx
