Sass compiling issue with Codekit and LiveReload

Hi,

I've installed the Aurora base theme and downloaded the latest Aurora gem without issue. Creating an initial sub-theme via the terminal seems to be fine too. The problem seems to occur when trying to compile an .scss file. I've not made any changes to the sub-theme at all - it's a vanilla install of Aurora with no grid.

Codekit gives me the following error on compile:

Compass was unable to compile one or more files in the project:
LoadError on line 161 of /Applications/Codekit.app/Contents/Resources/engines/compass/bin/.../lib/compass/configuration/data.rb: no such file to load -- aurora 

I then tried in LiveReload. The error pop-up showed the following:

error sass/ie.scss (Line 20 of _fluid-media.scss: Invalid CSS after "    @extend ": expected selector_sequence, was "%scaling-elemen...")
    error sass/print.scss (Line 20 of _fluid-media.scss: Invalid CSS after "    @extend ": expected selector_sequence, was "%scaling-elemen...")
    error sass/style.scss (Line 20 of _fluid-media.scss: Invalid CSS after "    @extend ": expected selector_sequence, was "%scaling-elemen...")

whilst the incorrectly compiled style.css contained the following info:

/*
Syntax error: Invalid CSS after "    @extend ": expected selector_sequence, was "%scaling-elemen..."
