I have tested this module in local system without Vbulletine.
Ads are not showing up here also. But it is counting viewing details properly.

It show following in debug output

sorry, permission issue.

Module is still not working with vbDrupal. But it is working with other vb and drupal integrations.
I have posted an issue with vb drupal.
