Problems with icons

Shall I get some help here?

<icon>

     <image16x16>icons/lit.png</image16x16>

     <image32x32>icons/notsolit.png</image32x32>

     <image48x48>icons/notlit.png</image48x48>

</icon>

I can't find any mistake on that code, simple, quick but still does not work.

Note: I've made myself a two-line BATCH file so I did not had to type "adl (...)-app.xml" 100 times, and I always start my AIR app with it.

Note 2: It's a HTML/JS App.

I've triple-checked major silly mistakes

Thank you for reading!
