Google Display Ad Error


I used the Adwords Export script to export a set of ads.

But when uploading to the Google Display Ad platform I get the following error:
"HTML5 ads created using DoubleClick Studio are not supported. To continue, please reach out to your Google representative about third party ad serving."

Clicking learn more doesn't give any specifics on the error.

Has anyone experienced this error? Any fixes?

Can you see if adding this line to the 'head' of your Hype document helps?
