AdSense question - why no ads?

[O Hammer O is my gamertag]

Ok, this page has ads - http://www.fpsgaming.us/halo_2_weapon_glitches.html

but not this page - http://www.fpsgaming.us/halo_2_general_weapon_info.html

And they both have lots of content and the ads code is the same. I just put the ads in today, could that be why?
