Millisecond Forums

Hi All,
I have set up a survey in Qualtrics and used the "redirection" feature to send people to millisecond to complete the AgeIAT (as the dependent measure in my study).  I seem to have done all of that correctly as I can see the Qualtrics ResposeID URL parameter at the end of the URL line in Millisecond.  From there obviously the participant is instructed to install the .dmg file to get inquisit on to their local machine before they can run the IAT.  The problem is that after this has all happened and the user hits the "START" button, the IAT does not run.  The entire IAT is skipped and the user is taken directly to the final screen as if the survey were over, where the message reads: 

The session is complete, and your data were successfully uploaded. Thank you for your participation!                      If you would like to uninstall the Inquisit Web plugin, click here.

Am I overlooking some thing pretty simple here? I have been through the inquisit web script wizard numerous times but I cannot see where I have gone wrong.  Any help would be most appreciated.

Thanks
Mike
