Auto-run disabled

Whenever I open a a character who I have rigged in rigify I get this strange error “Auto-run disabled,” a button that says reload trusted and the rig is all wrong. This is a problem when I send something to the render farm because I cannot manually reload the work when it calls up Blender. Is there a way to fix this?

User Preferences / File, enable ‘Auto Run Python Scripts’. Then save your user settings
