I noticed that in your screen capture, you did not open the folder labeled, "INSTRUCTIONS". Would there be any reason why you wouldn't do so?
I looked at their "Instructions" I talks about compatability, logo placement , sountrack, text changes--nothing that indicates what to import!
felt there was no need to show them as I assumed people would realize that's the first thing I would look at b4 asking for help--guess I was wrong
Watching your video, there is an After Effects project file titled "Main". Double click on it and it will open in After Effects.
I think Andrew has the right answer there. Double clicking the "Main" file will open the project in AE, and then allow you to edit and change the layers and settings as needed.
