[Plugin: Ad Injection] Issue with implementing different advert for each category

Hi and thanks for a great plugin that I’ve just started to use.

I would very much like to use the feature where you can implement different ads for each content category.

I’ve followed the instructions in the FAQ and created the sub folder ad-injection-ads in /wp-content/plugins/ad-injection-ads/

And I’ve uploaded a .txt file with the category name in which I want the ads content I put in the .txt file to be displayed. And I’ve put in the code show in the FAQ section into the ads box where I want the ad to be displayed.

My problem is that the ads script I put in the .txt file does not show in the category no matter what I do.

Am I doing something wrong here?
