Well Maarten,

I'm assuming you're referring to the editable version, though I'm not sure why the English version (say) has had its text converted to paths (font issues?). Sure, I can try that and see.

As a side note, you've got some serious licensing issues there: you can't just "add" licenses - CC-BY has to go as a start - and assuming we're calling this a derivative of all of the source files you're in fact into illegal territory because the GPL isn't compatible with a CC-BY-SA license AFAIK.

Regards, Harry
