Preloader problems

i did everything from the tutorial and changed only one thing. I made the preloader a scene and had it load to scene 2. first problem is, the bar doesn’t expand all the way for some reason when it hits 100. it only goes about 1/4 then stops. then when i try to put it on my website, i press the button the loads the movie in the “content” MC but the thing just stays black. I thought it was cause of loading but i don’t even see the preloader in there. any ideas?
