Can't update edx-platform after changing to Stanfor theme

[Jakub Wawrzyniak]

Hello

I'm running into an error while executing /edx/bin/update edx-platform master

Error goes as follows:
TASK [edxapp : checkout Stanford-style theme] **********************************
fatal: [localhost]: FAILED! => {"before": "e5dded82c2155f1f6521b9e353bc424a871cced3", "changed": false, "failed": true, "msg": "Local modifications exist in repository (force=no).", "warnings": []}

A little of background:
I tried to change the theme for my open edx platform (eucalyptus 3)

Whad did I do so far?
- Followed the steps at https://github.com/edx/edx-platform/wiki/Stanford-Theming
- Changed the theme/default/static to theme/stanford/static in .html files
- Changed _default.scss to stanford.scss
- Complied assets cms and lms


My server-vars.yml:

edxapp_use_custom_theme: true
edxapp_theme_name: 'stanford'
edxapp_theme_source_repo: 'git://github.com/Stanford-Online/edx-theme.git'
edxapp_theme_version: 'HEAD'

Any help will be much appreciated :)
