I'm working on enabling Adobe Target on our AEM site and I'm getting the following exception when trying to create a Target Activity in a given page. If I use an admin account it works fine so I'm thinking it's something permission related. I've granted permissions to the user I'm using when it fails with read/modify/create/delete/replicate to the /content/campaigns/cms path. What else am I missing to make this work?

java.lang.IllegalStateException: This tree does not exist
This group of users shouldn't have administrators rights. The target documentation mentions some steps when implementing target and I tried adding the target-activity-authors group to my group but it still didn't work.
