Hi Stephanie,
A few questions before I refer you over to our support group, to see if I can clear this up.
First: In Gatineau, is the website status green?
Second: Did you make sure the script was placed inside the <body> and </body> tags?
If both of those are true please contact support at https://support.adcenter.msn.com/eform.aspx?productKey=gatineau&ct=eformts . Refer to this discussion and we will continue working on the issue from there.
Thanks!
Brian
