Importepub plugin lucimoo moodle

I'm working with an old version of moodle(2.0.6) and I can't change this version. The problem is, when I install the [importepub plugin][1] and create a course it doesn´t show me the option import chapter from epub. I work with this versions: Moodle: 2.0.6 importepub: 0.16 [1]: http://lucidor.org/get.php?id=moodle-booktool_importepub-0.16.zip
