Topic: Can't open any of the .html files in Text Edit....HELP!!

I don't know what's up, but I have no problem opening up the gallery.xml files in text edit, but the .html files will not give me the source. I downloaded the customize file and just tried to open it...this is what I get:

This is the header. Download this example here.
SimpleViewer requires JavaScript and the Flash Player. Get Flash.
This is the footer

All the others I've made do the same and have background color, etc. I tried to just view my own source, cut and paste and that didn't work either. HELP! I just want to get a back button on my pages to go to a gallery directory.
