Try some of these things below:
My biggest mistake when I started was that I had neglected to FOLLOW an account. So, open the Aurasma app then click on the A at the bottom center of the screen to open up the Explore tabs in order to search for an account to follow. At the bottom of that screen you’ll see A, +, [ ], and magnifying glass. Select the magnifying glass which should open the search window. In the search window- type “SLJ” where you probably would see some photo icons and a colorful “A” marked SLJ for the SLJ account. Click on that colorful A -SLJ and you should open the SLJ page. On the upper right, make sure to tap “follow” (on iphone) or “like” on an ipad.

Once you have done that, you can exit the SLJ that screen by clicking on the [ ] “frame” to activate the camera.

Using the camera, point it up at the image. (Now that you are following the SLJ account all the Aura’s set up by SLJ will be triggered once you point your camera at the image, area etc. that SLJ has set up). SO, once you are following SLJ and scan the image of my library it should trigger a purple swirl and then a short video. *Note it may take a few seconds for your phone/ipad/android to download and play it.

If this didn’t work please reply here or contact me via twitter @pgoerner if you still need assistance. I’d love to know if it works for you, so please write either way!

Thanks ~ Phil G

PS- you can see who you are following by clicking the A to get the menu, then selecting the person at the bottom right. I’d suggest following Jill Compher, clicking on the links in the article then scanning some of her images for triggers. She has done some incredible stuff!
