nonfunctional TGB Behavior tutorial...

So I am working on the very most Basic TGB Behavior Mini Tutorial, the one that the introduction says that you should start with, and I find that none of the art assets that the tutorial requires are available...

That's ok. I can work around that. Those are just images.

So I progress on to adding the behaviors to the checker assets. The behaviors are also unavailable.

ok... so now the tutorial is unworkable. Unless I did something wrong when I set up (which I don't think that I did) then either that assets are just plain missing, need specific installation, or are possibly waiting for me to pay for the indye ver and get my registration number.

Does anyone have any thoughts on this that might help get me over this very basic hump?

Thanks.
