A quick check for the most recent version at the Adobe Exchange - I cannot find v2.5 which places InDesign and PDF files, only the pdf placer. (I believe you are using v2.5.) But there is a review that states that as of Feb 2014 the script is retuning a Javascript error. ID CC updated recently.
To my understanding, with a cloud subscription you have access to CS6; the script might (should?) work with CS6.
